What happens to the mercury in a thermometer Why?
The mercury in a thermometer expands and contracts as temperature changes. This expansion and contraction causes the level of mercury in the thermometer to rise or fall, providing a visual indication of the temperature.
A thermometer works on the principle that a rise in temperature causes?
A rise in temperature causes the particles in the thermometer to move faster, which in turn causes the liquid to expand and rise in the thermometer tube. This increase in volume is then calibrated to display a corresponding temperature reading.
Why the mercury level can rise or fall in a thermometer?
The mercury level rises in a thermometer when the temperature increases because heat causes the mercury to expand, pushing it up the tube. Conversely, the mercury level falls when the temperature decreases because the cooler temperature causes the mercury to contract, moving it down the tube.
Why does the mercury not fall or rise in a clinical thermometer when taken out of the mouth?
Mercury does not fall or rise in a clinical thermometer when taken out from the mouth because of the KINK present in it.
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 makes mercury go up and down a thermometer?
the heat and temperature that causes it to rise and fall.

How does a liquid thermometer show that you have a fever?
That type of thermometer has mercury in it, which is very heat sensitive. When used for taking a temperature, the heat from the body causes the mercury to rise. The amount the level of the mercury rises is determined by the body's temperature; the higher the temp, the higher the mercury rises.

How do you calculate the mercury rise in a thermometer?
To calculate the mercury rise in a thermometer, you need to subtract the initial temperature reading from the final temperature reading. The difference between these two readings represents the mercury rise in the thermometer. Make sure to use the units of measurement (usually degrees Celsius or Fahrenheit) in your calculation.
What causes liquid in thermometer to travel up and down in tube?
Heat causes Mercury in the thermometer to expand, where as when it is cooled, it contracts.
Why will the mercury in the thermometer rise after 3 minutes?
The mercury in the thermometer will rise after 3 minutes because it expands when exposed to heat. As the thermometer absorbs the heat of the environment, the mercury inside it will expand and move up the tube, indicating a higher temperature.
Why does the mercury in the thermometer go up when the temperature is high?
In a mercury thermometer, the mercury expands when it is heated, causing it to rise in the thermometer's narrow tube. This increase in volume is a physical property of mercury known as thermal expansion. The height of the mercury column in the thermometer is then used to measure the temperature.
What does an analog thermometer measure?
An analog thermometer measures temperature by using a liquid (like mercury or alcohol) that expands or contracts with changes in temperature, which causes the level to rise or fall in a narrow tube to display the temperature.
