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.
A thermometer works on the principle that a rise in temperature causes?
A rise in temp causes the expansion of the mercury or alcohol present in the tube.The graduation is done in such a way that the amount of expansion gives the temp.
The function of a Mercury thermometer?
to tell old people that have a mercury thermometer what the temperature is
Why does the Mercury in a thermometer appear red?
If the liquid in a thermometer is red it is not mercury, it is alchohol which has been colouired.
Why does alcohol in a thermometer rise?
Alcohol in a thermometer rises whenever the temperature of its surrounding increases. As the temperature increases, the heat causes the alcohol to expand ever so slightly, which shows up as an increase of height of the alcohol in the tube of the thermometer.
What makes mercury go up and down a thermometer?
the heat and temperature that causes it to rise and fall.

Mercury does not fall or rise in a clinical thermometer when taken out from the mouth because of the KINK present in it.
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.

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.
What is the definition of Glass thermometer?
thermometer consisting of mercury contained in a bulb at the bottom of a graduated sealed glass capillary tube marked in degrees Celsius or Fahrenheit; mercury expands with a rise in temperature causing a thin thread of mercury to rise in the tube
How does Mercury work?
Temperature affects the amount the mercury is spread out. Heat causes most liquids to expand, which is how a thermometer works. As heat around the glass protecting the mercury of the thermometer rises, the mercury expands and covers more room in the thermometer.
What causes mercury in a thermometer to separate?
The cause is an udesired absorption of air.
How do you test the temperature of the air?
Get a thermometer - the mercury will rise or fall accordingly to the temperature of the air.
Why the mercury can not rise in a lab thermometer if there is air in the 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 glass tube?
Because the pressure of air may be greater than the pressure of the ascending Mercury.
Why will the mercury in the thermometer rise after 3 minutes?
It will rise from the moment it is heated - for example, from the moment it has contact with the body. But it is expected to stabilize after a few minutes.
