- In a Mercury thermometer, the level of mercury falls as the temperature of the air around it cools.
- A mercury thermometer has a bulb of mercury at the bottom and a thin tube above it with markings in Celsius degrees or Fahrenheit degrees. When the temperature warms, the mercury expands and rises up the tube. When the temperature cools, the mercury contracts and shrinks back toward the bulb at the bottom.

What is a mercury filled glass tube that measures air temperature called?
A mercury-filled glass tube that measures air temperature is called a mercury thermometer.
What is in a thermometer and a barometer?
A thermometer measures temperature - most are now electric but they used to have alcohol or mercury in them. A barometer measures air pressure - they are now electric but used to have air in them (in a bellows with a spring).
What helps a mercury in glass thermometer to respond quickly to change in temperature?
The thin glass tube and small bulb containing mercury in a mercury-in-glass thermometer allows for quick thermal equilibrium with the surrounding air. This design enables the mercury to rapidly expand or contract in response to temperature changes, causing the height of the mercury column to fluctuate and accurately indicate the temperature.
Would the mercury in a broken thermometer be enough to contaminate the air in a classroom above acceptable levels?
It is unlikely that the amount of mercury in a single thermometer would be enough to significantly contaminate the air in a typical classroom. However, it is important to properly clean up and dispose of any spilled mercury to prevent exposure to harmful levels. If there is a spill, follow appropriate cleanup protocols and ensure proper ventilation in the area.
What should be done to enable a mercury in a glass thermometer to respond quickly to changes in temperature?
To enable a mercury in a glass thermometer to respond quickly to temperature changes, it should be designed with a thinner glass casing to improve thermal conductivity. Placing the thermometer in direct contact with the surface being measured can also help it respond faster. Lastly, ensuring that the mercury is free from air bubbles can improve its responsiveness to temperature fluctuations.
What happens to the mercury in the thermometer when the air gets warm?
mercury explodes
Does mercury stay in the tube or escape into the air?
Mercury stays contained in the tube of a mercury thermometer when in use. It does not escape into the air as long as the thermometer is intact. However, if the thermometer is broken or improperly disposed of, mercury vapor can be released into the air, which is harmful to health.
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.
What is a mercury filled glass tube that measures air temperature called?
A mercury-filled glass tube that measures air temperature is called a mercury thermometer.
What causes mercury in a thermometer to separate?
The cause is an udesired absorption of air.
Is there air in a glass thermometer?
Yes, above the mercury or the other liquid.
Why the mercury can not rise in a lab thermometer if there is air in glass tube?
Because the pressure of air may be greater than the pressure of the ascending Mercury.
Why the mercury can not rise in a lab thermometer if there is air in the glass tube?
Mercury does not rise in a lab thermometer if there is air in the glass tube because the presence of air creates pressure within the tube that opposes the expansion of the mercury. Without a vacuum, the air pressure prevents the mercury from moving freely up the tube in response to changes in temperature.
What is mercury contained in a tube used to measure air temperature called?
thermometer
Why the reading of thermometer is taken when the mercury stop expanding?
The mercury will expand and rise up the thermometer tube until it reaches the temperature of the air around it. When it stops expanding, it is the same temperature as the air, and therefore gives an accurate reading.
How do you test the temperature of the air?
You can test the temperature of the air using a thermometer designed for measuring air temperature. Simply place the thermometer in the area where you want to measure the temperature and read the display. Be sure to avoid blocking the airflow around the thermometer for an accurate reading.
What instrument measures changes in temperature?
Temperatures are measured by instruments called thermometers.The instrument usually used to measure air temperature is the maximum-minimum thermometer. It consists of a U shaped tube with bulbs at each end and mercury at the bottom. Air heats or cools the bulbs causing the air inside to expand or contract, therefore pushing or pulling the mercury upwards or downwards.There are 3 types of thermometer: minimum thermometer, maximum thermometer,and the "Six's thermometer" -- these record the temperatures over a period of time.it says in my book that a thermometer measures air temperature
