Mercury thermometers work on the principle that mercury expands when heated and contracts when cooled. The scale on the thermometer is calibrated based on this expansion and contraction, allowing it to measure temperature accurately. When the temperature rises, the mercury expands and rises up the tube, and when the temperature falls, the mercury contracts and moves back down the tube.

What is the working principle of a liquid in glass thermometer?
A liquid-in-glass thermometer works based on the principle of thermal expansion. As temperature increases, the liquid inside the thermometer expands and rises in the calibrated glass tube. The level of the liquid indicates the temperature which corresponds with a specific scale on the thermometer.
What color is the Mercury in a Mercury thermometer?
Mercury in a Mercury thermometer is typically silver in color.
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.
How does Anders Celsius'e thermometer work?
Anders Celsius' thermometer works based on the principle that liquids expand when heated and contract when cooled. The mercury or alcohol inside the thermometer rises or falls in a calibrated tube to indicate changes in temperature. Celsius defined the scale so that 0 degrees represents the freezing point of water and 100 degrees represents the boiling point of water.
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.
What is the working of the thermometer?
capillarity rise.heating expands mercury whereas cooling contracts 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 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.
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.
Why does Mercury in the the thermometer rise?
Mercury rises in a thermometer when the temperature increases because mercury expands as it heats up. This expansion of the mercury column inside the thermometer is used to measure the temperature of the surrounding environment.
What is the sSensor in Mercury-in-glass thermometer?
The sensor in a mercury-in-glass thermometer is the glass bulb at the base of the thermometer containing the mercury. The temperature is measured by the expansion or contraction of the mercury based on the surrounding temperature, allowing the thermometer to provide a temperature reading.
