Can flow from higher level to lower level?
Liquids are heavier than air and are affected by gravity. Due to the pressure difference also they flow down.
How is gas condensed?
Condensation commonly occurs when a vapor is cooled and/or compressed to its saturation limit when the molecular density in the gas phase reaches its maximal threshold. Vapor cooling and compressing equipment that collects condensed liquids is called a “condenser”.
Why do gases flow in all directions for Class 3?
Gases flow in all direction because of high intermolecular space.
Why the water doesn’t flow from the glass?
Pressure is not the reason why water will flow. Since the bottom of the glass is closed, there will be no flow of water. This is because the container will exert a force on the water equal to the weight of the water in opposite direction to the weight, which means upwards.
Which of the following liquid will flow the slowest?
One of the reasons it took so long to identify tar pitch as the slowest-moving liquid on the planet is because it looks like a solid at room temperature.
Why do gases easily flow?
Answer. Particles of gas move freely as there is lot of space and they have more kinetic energy than liquids and solids. Gases have the highest rate of diffusion.
Which of these substances flow from higher level to a lower level?
Answer: fluids ( liquid and gases) flow from higher level to lower level.
Does gas flow easily?
Gas. The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds.
Does gas flow yes or no?
Definite shape | definite volume | |
---|---|---|
liquid | no | yes |
gas | no | no |
Can air be compressed in a syringe?
Air acts somewhat like a spring. You can compress it, or squeeze it into a smaller volume. When you push on the plunger you can feel the air pushing back. When you stop pushing, the air inside the syringe will return to its original size.
Can you compress a gas into a solid?
The short answer is yes. You may want to google the term “Phase Diagram” for the particular material that you want to compress. With most material, there’s a transition to the liquid phase before going into the solid phase.
Why do drinks spill when pouring?
The simple answer is surface tension. Say you’re pouring water out of a pitcher. Surface tension is causing it to stick to the pitcher.
Is liquid can be compressed?
A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds. Like a gas, a liquid is able to flow and take the shape of a container. Most liquids resist compression, although others can be compressed.
What will happen if I drop a container while water is pouring out of it?
Liquid flowing down the side of the container
When pouring tea or water out of a container (especially when you do it slowly), the attraction between the surface and the water molecules is stronger than that of the water molecules among themselves.
Why does water stick to itself?
Cohesion: Hydrogen Bonds Make Water Sticky
Water has an amazing ability to adhere (stick) to itself and to other substances. The property of cohesion describes the ability of water molecules to be attracted to other water molecules, which allows water to be a “sticky” liquid.
What is the lightest state of matter?
Aerogels are the lightest solids and have a density of 1.9 mg per cm3 or 1.9 kg/m3 (526.3 times lighter than water). Sometimes called frozen smoke, aerogels are open-cell polymers with pores less than 50 nanometers in diameter.
Which liquid can climb up the wall of the glass vessel?
The property of being able to flow without any loss of kinetic energy is called Superfluidity. These fluids are able to climb up the walls of the container they are kept in due to 0 viscosity. Superfluidity is found to occur in isotopes of helium.
Is glass the slowest moving liquid?
Glass is not a slow-moving liquid. It is a solid, albeit an odd one. It is called an amorphous solid because it lacks the ordered molecular structure of true solids, and yet its irregular structure is too rigid for it to qualify as a liquid.
Which of the following liquids can climb up the wall of the glass vessel in which it is placed?
Liquid helium behaves as superfluid, and defies gravity and thus can climb up the wall of glass vessels.
What has lower viscosity than water?
8cST) fluid. Everything I have come across that is low viscosity is inflammable – acetone, ether, silicone oil, fuel, etc. I have found some confusing things in my research. Acetone has a viscosity 3x less than water but weighs 2.5 times more.
Which liquid flows faster?
Physicists surprised to find that in specially coated tubes, the more viscous a liquid is, the faster it flows. It’s widely known that thick, viscous liquids — like honey — flow more slowly than low-viscosity liquids, like water.
Do gases have the ability to flow?
The gas behaves like a liquid; the particles are moving but are still attracted to each other, so they still flow. Unlike a solid or a liquid, the gas will try to fill whatever container it is in, adapting its volume accordingly.
What is the ability to flow of gas?
First, liquids share the ability to flow with gases. Both liquid and gas phases are fluid, meaning that the intermolecular forces allow the molecules to move around. In both of these phases, the materials don’t have fixed shapes and instead are shaped by the containers holding them.
What happens to the particles in a gas when it becomes a liquid?
If a gas is cooled, its particles will eventually stop moving about so fast and form a liquid. This is called condensation and occurs at the same temperature as boiling. Hence, the boiling point and condensation point of a substance are the same temperature.
What flows easily?
The forces between liquid particles are weaker than the forces between solid particles. This means that liquid particles are further apart and can move about more easily. Since the particles can move, the liquid can flow and take the shape of its container.
Why does the volume of a gas decrease as the pressure is increased at constant temperature?
It means that for a gas at a constant temperature, pressure × volume is also constant. So increasing pressure from pressure 1 to pressure 2 means that volume 1 will change to volume 2, providing the temperature remains constant.
How do gas particles move?
In gases the particles move rapidly in all directions, frequently colliding with each other and the side of the container. With an increase in temperature, the particles gain kinetic energy and move faster.
Can gas be squashed?
Properties of Materials: Gases
Materials in a gaseous state can spread out to completely fill the container or room they are in. Gases have weight. Gases can be squashed. Gases do not keep their shape.
Does volume of air increase when more air added?
As the balloon is made out of an elastic material, the balloon gets larger as more air is blown into the balloon. As the size of the balloon increases, the volume of gas in the balloon also increases. This is another example of EXPANSION.
What happens when a gas becomes ionized?
Gas turns into plasma when heat or energy is added to it. The atoms that make up the gas start to lose their electrons and become positively charged ions. The lost electrons are then able to float freely. This process is called ionization.
Can gases change volume?
Gases, for example, do not have a fixed volume * or shape. As a result, gases respond to pressure changes by changing their volume. In other words, gases are compressible.
Does the mass of air change when compressed?
Q1) The air’s mass remains the same because it is the same amount of air just compressed.
Why are solids not compressible?
Solids are a type of matter with tightly bonded atoms due to strong intermolecular forces of attraction. They retain a fixed volume and shape. They are not easily compressible as there is little space between particles. They are rigid and cannot be shaped and cannot be compressed.
Can you crush water?
Answer. The answer is yes, You can compress water, or almost any material. However, it requires a great deal of pressure to accomplish a little compression. For that reason, liquids and solids are sometimes referred to as being incompressible.
Are cats liquid?
According to Wikipedia, “liquid takes the shape of a container” and maintains “almost-fixed volume.” So there you have it. Cats are liquids! However, unlike water, these funny cats do not merely show the properties of liquid – they love to do so.
Is water wet?
If we define “wet” as “made of liquid or moisture”, then water is definitely wet because it is made of liquid, and in this sense, all liquids are wet because they are all made of liquids.
Why do gases show high compressibility?
There is no space between the individual particles, so they cannot pack together. The kinetic-molecular theory explains why gases are more compressible than either liquids or solids. Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles.
What happens when a gas squeezes into a smaller space?
Answer. If we apply pressure on gases ( i.e. squeeze them into smaller space ) below the critical point They get CONVERTED into LIQUID STATE. It because when we compress them there molecules come near, develop bonds and build up stronger intermolecular force thus, forming Liquids.
Have you ever tried to compress the gas in a syringe Why do you think the gas can easily be compressed?
Gases can be easily compressed as compared to solids and liquids because in gases, the particles are far apart than in solids and liquids.
How do you pour without dribbling?
Tilt the container containing the liquid quickly when you start pouring it. This will prevent the liquid from dripping along it’s sides. Hold a long handled spoon vertically in the centre of the empty container into which you want to pour the liquid with one hand.
Why does water stay in the glass?
Scientists call this atmospheric pressure. When you flip the water glass over in this experiment, the water in the glass is pulled down by gravity. But, the force of the water pushing down is lower than the force of atmospheric pressure, which is pushing up on the card. That’s why the water stays in the glass.
What happens to a liquid when placed in a container and left inside the freezer overnight?
Freezing is the process that causes a substance to change from a liquid to a solid. Freezing occurs when the molecules of a liquid slow down enough that their attractions cause them to arrange themselves into fixed positions as a solid.
When you removed your finger at the hole and at the same time drop the cup what happened?
First off, when you just held the cup and let your finger off the hole, the water was pulled down by gravity and thus water pressure pushes it out the hole. So what changes when you drop the cup and water? The cup and water begin falling at the same speed, and are actually weightless as they fall.
Can water go through microscopic holes?
Water likes to stick together, so it takes effort to separate a stream of water from a body of water. Unless you press the bottle—or unless the air in the atmosphere pushes on the top surface of the water—no streams will flow out from tiny holes.
Can you drop sand into the water in the glass without spilling it Why or why not?
This attraction causes the molecules to stick together and avoid spilling down the side of the glass like gravity would like them to. Unfortunately, the attraction between the water molecules is only so strong.
Is water polar?
Water is a Polar Covalent Molecule
The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles – a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side).
Why does ice float on water?
What’s so special about ice that causes it to float? Believe it or not, ice is actually about 9% less dense than water. Since the water is heavier, it displaces the lighter ice, causing the ice to float to the top.
Is there a 5th state of matter?
There are four states of matter common in everyday life — gases, liquids, solids, and plasmas. However, there is also a fifth state of matter — Bose-Einstein condensates (BECs), which scientists first created in the lab 25 years ago.
Is water the only liquid?
Water is the only common substance that is naturally found as a solid, liquid or gas. Solids, liquids and gases are known as states of matter. Before we look at why things are called solids, liquids or gases, we need to know more about matter.
Why do liquids flow from higher level to lower level?
Liquids are heavier than air and are affected by gravity. Due to the pressure difference also they flow down.
What can flow from higher to lower level?
Answer: fluids ( liquid and gases) flow from higher level to lower level.
Which of the following liquid will flow the slowest?
One of the reasons it took so long to identify tar pitch as the slowest-moving liquid on the planet is because it looks like a solid at room temperature.
Do gases have high or low viscosity?
Viscosity is measured using a viscometer. Measured values span several orders of magnitude. Of all fluids, gases have the lowest viscosities, and thick liquids have the highest.
Is gasoline less viscous than water?
Water, gasoline, and other liquids that flow freely have a low viscosity. Honey, syrup, motor oil, and other liquids that do not flow freely, like those shown in Figure 1, have higher viscosities.
