Mercury does not touch the walls of a thermometer because it expands when heated, filling the space within the thermometer tube without coming into contact with the walls. This expansion is what allows mercury to accurately measure changes in temperature by rising and falling within the tube.
What else can I help you with?
What color is the Mercury in a Mercury thermometer?
Mercury in a Mercury thermometer is typically silver in color.
What should you do if you break a mercury thermometer?
If you break a mercury thermometer, do not touch the mercury with your bare hands. Use gloves and carefully pick up the mercury beads with a piece of paper or cardboard. Place the mercury in a sealed container and contact your local environmental agency for proper disposal instructions.
Can the mercury in a thermometer hurt you?
Yes, if a mercury thermometer breaks, the mercury can vaporize and be inhaled, which can be harmful to your health. It is important to handle and dispose of a broken mercury thermometer properly to avoid exposure to mercury.
What happens when you touch thermometer Mercury?
If a mercury thermometer breaks and you come into direct contact with the mercury, it is important to clean it up carefully. Do not touch the mercury with bare hands and do not use a vacuum cleaner. Wear gloves and use a paper towel to carefully clean up the mercury, then dispose of it properly according to local hazardous waste regulations. It is important to minimize exposure to mercury as it is toxic when ingested or inhaled.
What causes mercury in a thermometer to rise?
The mercury in a thermometer rises because of thermal expansion. When the temperature surrounding the thermometer increases, the molecules of the mercury expand, causing it to move up the narrow tube of the thermometer.
Where can you get mercury?
From a thermometer. Note! Mercury can enter your body through the skin and there is no ay to remove it. Don't touch it!!

Why shouldn't the thermometer touch the walls of the distillation head?
because the sides of the beaker will be slightly at high temperature
Why does mercury not flow down when the mercury thermometer is held upside down?
Mercury is a dense liquid at room temperature, so gravity is not strong enough to overcome the surface tension and adhesion forces holding it in place inside the thermometer tube. This allows the mercury to "stick" to the walls of the tube and not flow down when the thermometer is turned upside down.
Can the mercury in a thermometer hurt you?
Yes, if a mercury thermometer breaks, the mercury can vaporize and be inhaled, which can be harmful to your health. It is important to handle and dispose of a broken mercury thermometer properly to avoid exposure to mercury.
What is Mercury thermometer use to measure?
A mercury thermometer is used to measure temperature.
Mention any two points of difference between a clinical thermometer and an ordinary mercury thermometer?
A clinical thermometer will offer more precise calibrated readings than a mercury thermometer. The range of measurable temperature differs between a clinical and a mercury thermometer with the mercury thermometer having the wider range.
What happens when you touch thermometer Mercury?

What is the most dangerous thermometer if it breaks?
A mercury thermometer is the most dangerous if it breaks because mercury is a toxic substance that can harm human health and the environment. If a mercury thermometer breaks, it is important to follow proper cleanup procedures to avoid exposure to the mercury.
How is mercury in a thermometer poisonous?
Mercury in a thermometer is poisonous if it is inhaled or ingested. When a thermometer breaks, mercury vapor can be released into the air, which can be harmful if breathed in. Additionally, if mercury is ingested, it can be absorbed into the bloodstream and cause poisoning.
