What’s the liquid inside a Galileo thermometer?
ethanol What is the clear liquid in a Galileo thermometer? The clear liquid in a Galileo thermometer is ethanol, a colorless volatile liquid with very little odor. Although its density is less than water, it varies depending on the temperature, even more so than water.
Is liquid inside Galileo thermometer toxic?
R65: Harmful: may cause lung damage if swallowed.
How do you clean 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.
How do you dispose of a broken mercury thermometer?
The preferred method of disposal for unbroken mercury thermometers and the mercury from broken thermometers is to take them to a local household hazardous waste collection facility or thermometer collection site if one is available in your area.
Does a Galileo thermometer have mercury in it?
No, there is no mercury in a Galileo thermometer. A Galileo thermometer consists of a vertical glass tube containing water with several different…
What is Galileo thermometer made of?
A Galileo thermometer (or Galilean thermometer) is a thermometer made of a sealed glass cylinder containing a clear liquid and several glass vessels of varying density.
What should you do if you spill mercury?
Avoid spreading spilled mercury! Avoid walking through the spill area. Take children and pets to another room. Leave any clothing or footwear that came into contact with the spilled mercury in the affected room. If possible, close the doors of the room with the spilled mercury to keep vapors from spreading.
How do you get rid of mercury vapor?
Shut down or close off vents that could spread mercury vapors to other areas. Open exterior windows to ventilate any mercury vapors to the outdoors. If possible, place a fan in a window to blow the vapors out but avoid breezes that might blow the mercury vapor back indoors or into other nearby residences.
What if I touched mercury from a thermometer?
MERCURY EXPOSURE 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.
Can you get mercury poisoning from a broken thermometer?
A broken mercury-containing thermometer can be toxic if the vapors are inhaled. The risk of poisoning from touching or swallowing mercury from a broken thermometer is low if appropriate clean-up measures are taken.
How do you clean up spilled mercury?
Sprinkle sulfur powder over the contaminated area and rub it gently all over the surface and into the cracks with a paper towel. Sulfur powder binds with mercury. Use a paper towel dampened with water followed by wiping with another damp paper towel to clean up the sulfur and mercury.
Why Galileo thermometer is not accurate?
There is also the minor detail that Galileo thermometers are not exactly precision instruments. A small one can have 6 degrees (F) of difference between the balls, which make for quite a measurements range of error. Even larger models have at least a couple of temperature difference between the diver globes.
Do Galileo thermometers have mercury in them?

Can you get mercury poisoning from broken thermometer?
A broken mercury-containing thermometer can be toxic if the vapors are inhaled. The risk of poisoning from touching or swallowing mercury from a broken thermometer is low if appropriate clean-up measures are taken.
Does mercury vapor go away?
At room temperature, exposed elemental mercury can evaporate to become an invisible, odorless toxic vapor. This vapor has a very long life (up to one year) in the air.
How long does mercury vapor stay in the air?
one year They can go through small cracks or become strongly attached to certain materials. At room temperature, exposed elemental mercury can evaporate to become an invisible, odorless toxic vapor. This vapor has a very long life (up to one year) in the air.

How long does it take for a mercury drop to evaporate?
384 days A pea-sized drop of mercury that goes undetected can take up to 384 days to fully vaporize. In that amount of time, it can cause severe neurological damage—especially in infants and children.
Where is the best place to put a Galileo thermometer?
Hang your Galileo thermometer indoors and from a hook. For the most accurate results, it's best to not hang the thermometer in direct sunlight. Allow a few minutes for the floating spheres within the thermometer tube to rise and fall according to the current temperature.
What is the liquid in a thermometer?
In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers can be used to determine body, liquid, and vapor temperature.
What is a Galileo thermometer made of?
A Galileo thermometer (or Galilean thermometer) is a thermometer made of a sealed glass cylinder containing a clear liquid and several glass vessels of varying density.
How do you clean mercury off the floor?
Sprinkle sulfur powder over the contaminated area and rub it gently all over the surface and into the cracks with a paper towel. Sulfur powder binds with mercury. Use a paper towel dampened with water followed by wiping with another damp paper towel to clean up the sulfur and mercury.
How do you remove mercury vapor from air?
Isolate the spill and ventilate the area Use fans to blow mercury-contaminated air outside. Close or cover all heat vents and cold air returns. Turn off fans that don't vent outside. Turn off any space heaters and central heating to cool the room and keep mercury from circulating inside the house.
How do you clean mercury from the air?
Ventilate Open all windows and close internal doors of the room for 15 minutes before you attempt to clean up. Turn off heating to reduce vapours. Turn off ducted heating or air-conditioning to prevent vapours circulating to other parts of the house.
