What chemicals are in a Galileo thermometer?
The liquid in a Galileo thermometer is water. Floating in the water within the tube are glass bubbles also filled with water containing simple food coloring, though sometimes alcohol might be used. The Galileo thermometer is an accurately functioning machine that is more often than not used today as decoration.
Which thermometer does not contain mercury?
Spirit thermometers use a non-toxic alcohol instead of mercury to register the temperature. Like liquid mercury, the alcohol expands in volume as it gets warmer, causing the liquid to move up the thin tube inside the glass thermometer. Digital thermometers contain a device called a thermoresistor.
Do thermometers still have mercury in?
The oldest thermometers used are mercury in glass. Newer thermometers include non-mercury liquids in glass and digital and electronic devices that use sensors to measure temperature. Thermometers that check body temperature in the ear, across the forehead, or have a digital display do not contain mercury.
How can you tell if a thermometer is mercury?
- If there is no liquid in your thermometer, for example, if it uses a metallic strip or coil to measure temperature (like most meat thermometers do), it is not a mercury thermometer.
- If the liquid in the thermometer bulb is any color other than silver, it is not a mercury thermometer.
Can mercury from a thermometer hurt you?
Mercury vapor is not irritating and has no odor, so people do not know when they are breathing it. Even the small amount of mercury from a broken thermometer can cause harm, especially to children, unless it is properly cleaned up and removed.
How much mercury is toxic from a thermometer?
Each thermometer contains about . 5-1.5 grams of mercury. One gram of mercury can contaminate a 20 acre lake, enough to cause a public advisory to be issued on the potential dangers of eating fish caught in that lake.
What chemicals are in liquid thermometers?
Most commercial liquid-in-glass thermometers are filled with mercury or an alcohol such as ethanol. Both liquids have their limitations: Mercury is volatile and toxic, whereas ethanol has a relatively short range between its freezing and boiling points.
Is there enough mercury in a thermometer to hurt you?
Mercury is a very toxic or poisonous substance that people can be exposed to in several ways. If it is swallowed, like from a broken thermometer, it mostly passes through your body and very little is absorbed. If you touch it, a small amount may pass through your skin, but not usually enough to harm you.
What replaced mercury in a thermometer?
Others include the thermistor and the thermocouple. Non-mercury organic-liquid-filled-glass thermometers are also a replacement for mercury thermometers.
Are digital thermometer mercury free?

Are mercury thermometers legal?
Since 2001, 20 states have banned mercury “fever thermometers” for medical use, and regulations tighten every year. Many pharmacies now carry only sterile digital replacements or the less accurate ones with red glop in the bulb.
Which of the following thermometer contains mercury?
General Science
Basal Thermometer or clinical thermometer contains mercury about 2.25 grams.
Which thermometer does not use mercury 7?
Digital thermometer
Digital thermometers do not use mercury and hence safe to use.
How do you clean up mercury from a broken thermometer?
Slowly and carefully squeeze mercury onto a damp paper towel. Alternatively, use two pieces of cardboard paper to roll the mercury beads onto the paper towel or into the bag. Place the paper towel in a zip locking bag and secure. Make sure to label the bag as directed by your local health or fire department.
Do outdoor thermometers contain mercury?
Outdoor thermometers can be analog or digital. Analog thermometers use thermosensitive liquids or metals. Analog thermometers have glass tubes filled with bright-colored liquids, or mercury, and have degrees marked along the side.
Do red thermometers have mercury?
How can I tell if my thermometer has mercury? Mercury is a silver-white to gray substance. If your thermometer is filled with a red liquid, your thermometer contains red dyed alcohol or mineral spirits and not mercury. These are safer alternatives to mercury fever thermometers.
What happens if you break a mercury thermometer?
When elemental mercury is spilled or a device containing mercury breaks, the exposed elemental mercury can evaporate and become an invisible, odorless toxic vapor. This happens with the most known devices such as barometers, blood pressure gauges, thermometers, etc.
How much mercury is present in thermometer?
A typical mercury thermometer contains approximately 0.7 grams of mercury (700 milligrams), but larger thermometers can contain as much as three grams. Both short term and long term exposure to mercury can cause serious health problems for humans and wildlife. How toxic is mercury?
What gets rid of mercury?
Recycling and Disposal Options
Many states and local agencies have developed collection/exchange programs for mercury-containing devices such as thermometers, manometers, and thermostats. Some counties and cities also have household hazardous waste collection programs.
What happens if you touch mercury?
Mercury does not absorb through your skin instantly. Elemental mercury does absorb through your skin, but at a very slow pace (very slowly). As long as you don’t expose your skin to the metal too much and you wash your hands after then you would be fine.
Can mercury be absorbed through the skin?
ROUTES OF EXPOSURE: Elemental mercury is toxic primarily through inhalation of mercury vapors. It is only slowly absorbed through the skin, although it may cause skin and eye irritation. Elemental mercury droplets may be absorbed through eye contact.
What states have banned mercury thermometers?
As a result, a number of states have banned or limited the sale of mercury thermometers, including California, Oregon, Rhode Island, Maine, Maryland, Indiana, Minnesota, and New Hampshire.
Why are glass thermometers not recommended?
Disadvantages. Liquid in glass thermometers tend to be fragile and hence easily broken, can only be used where the liquid column is visible, cannot be used for surface temperature measurements, cannot be read from a distance and are unsuitable for high temperature measurements.
Which is better digital thermometer or mercury thermometer?
1. Digital thermometers provide faster results. Digital thermometers provide fast results as opposed to mercury thermometers whose readings are slower to realize because you have to wait for the mercury to heat and then slowly rise to display the temperature.
What are the disadvantages of digital thermometer?
- Digital thermometers have the disadvantage of having dead batteries.
- Submerging a conventional thermometer in warm, soapy water is simple, but doing it with a digital thermometer is more complicated.
- Some digital thermometers are more accurate than others.
Why can’t doctors use laboratory thermometers?
Why can’t we use a laboratory thermometer to measure the body temperature? Because it does not have a kink. Its range does not include the body temperature range. It is difficult to handle.
Are digital thermometer more accurate than mercury?
The digital thermometer is not only faster on body temperature measurement results providing, but also better accuracy results to us. Based on the tested records of the experiments, the accuracy of a digital thermometer could be 0.1℃. The accuracy is better than the normal mercury thermometer.
When did they stop making mercury thermostats?
manufacturers in the U.S. – General Electric, Honeywell, and White-Rodgers. These companies reported that they phased-out the manufacture and sale of mercury-added thermostats in October 2009. Since 2001, many states have passed legislation restricting the sale of mercury-added thermostats.
Why do thermometers have mercury?
Mercury is the only one in liquid state at room temperature. It’s used in thermometers because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it’s used in a thermometer. It also has a high boiling point which makes it very suitable to measure higher temperatures.
Why there is no kink in laboratory thermometer?
In laboratory thermometer, the temperature is measured continuously to note temperature change. Thus the continuous movement of mercury is required without any flow break. Therefore, a laboratory thermometer does not have a kink.
What is difference between laboratory and clinical thermometer?
A clinical Thermometer is meant for clinical purposes. It is developed for measuring the human body temperature. A laboratory thermometer, which is colloquially known as the lab thermometer, is used for measuring temperatures other than the human body temperature.
What color is mercury thermometer?
The color of mercury in the thermometer is silver.
What is the difference between mercury and alcohol thermometer?
Alcohol thermometer and mercury thermometer are two types of thermometers which are composed of a bulb and a marked glass tube. The main difference between alcohol and mercury thermometer is that the bulb of mercury thermometer is filled with mercury whereas the bulb of alcohol thermometer is filled with an alcohol.
Are mercury free oral thermometers accurate?
Non-mercury thermometers have scale divisions equal to mercury thermometers. Most range from 0.5° to 1° C. Accuracy limits for non-mercury thermometers below 150° C are also compatible with mercury thermometers; accuracy is typically ± 1° – 2° C.
Does mercury stay in your body forever?
Mercury does not stay in the body forever. It takes about six months to a year to leave the bloodstream once exposure stops. Some researchers think mercury can permanently damage the nervous system in children.
Can mercury poisoning be healed?
There’s no cure for mercury poisoning. The best way to treat mercury poisoning is to stop your exposure to the metal. If you eat a lot of mercury-containing seafood, stop immediately.
How fast is mercury poisoning?
Poisoning from methylmercury can take weeks or months to appear. A chemical spill with elemental mercury or inorganic mercury might give you symptoms more rapidly. Mercury poisoning is diagnosed by testing your blood and urine for mercury levels. Urine might be collected over a 24-hour period.
Can you handle mercury with bare hands?
The chemical element mercury (Hg) is sometimes called quicksilver because of its liquid metallic appearance. While the sight of metal pouring from the hand is intriguing, mercury is extremely toxic when inhaled or touched and should never be handled with bare skin.
What happens when mercury touches gold?
Freddie Mercury may have had the golden voice, but real mercury, that endlessly entertaining and dangerous liquid metal, has the golden touch. That is, if it touches gold it will immediately break the lattice bonds of the precious metal and form an alloy in a process known as amalgamation.
What STD was treated with mercury vapor?
Mercury was in use by the early 16th century, and remained the primary treatment for syphilis until the early 20th century. Syphilis led to stigmatizing disfigurations that were treated with surgery, including pioneering attempts in rhinoplasty.
How do I know if my thermometer has mercury in it?
If the liquid in the thermometer bulb is any color other than silver, it is not a mercury thermometer. If the liquid in your thermometer bulb is silver, then the liquid might be: Mercury. A non-toxic compound that looks similar to mercury.
