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 the fluid inside 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.
How does a Galileo thermometer work?
Galileo thermometers work on the principle of buoyancy, which determines whether objects float or sink. As the temperature changes, the glass balls will either sink to the bottom (temperature rises), or float to the top (temperature falls).
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.
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.
Is the red stuff in thermometers?
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. Are there any special precautions I need to take when bringing in the thermometer?
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 does a liquid in a glass thermometer work?
Liquid-in-glass thermometers are based on the principle of thermal expansion of substances. A liquid in a glass tube (called a capillary) expands when heated and contracts when cooled. A calibrated scale can then be used to read off the respective temperature that led to the corresponding thermal expansion.
How do you fill a Galileo barometer?
1) Fill a container with water — use distilled water to help prevent streaks on the glass. 2) Add food coloring to the water to make it easier to see. 3) Push the injection tube onto the syringe (shown below). 4) Fill the syringe with the colored water.

Does a thermometer have mercury?
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 do you fill a barometer with water?
This device can be filled using a combination of hot and cold water, and is best to fill on a good day when the local pressure reads 30 and above. Submerse the barometer completely in the hot water until bubbles stop coming out of the spout. Place a finger over the spout and move the barometer to the cold water.
