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.
Which thermometer is a greater health hazard if it breaks Is it the mercury in glass or alcohol in glass thermometer?
Mercury is poisonous.
Why can a mercury thermometer be used only at high temperatures?
A mercury thermometer can go down to -30 deg C
Why do you like Mercury?
i like mercury because it is inside a thermometer
Is the external bulb of a thermometer also made of mercury?
The red liquid in a thermometer is Mercury, which is usually encased in a glass 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.
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 do you test the temperature of the air?
Get a thermometer - the mercury will rise or fall accordingly to the temperature of the air.
What makes mercury go up and down a thermometer?
the heat and temperature that causes it to rise and fall.
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.
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 the liquid in a thermometer changes so that it can be sued to measure temperatures?
The thermometer is a sealed glass tube containing mercury in a vacuum. The mercury column will rise or fall due to expansion, and the level is read off a temperature scale.
Why does mercury level goes down for a very short time when a mercury-in glass thermometer is placed in hot water?
The exterior of the bulb of the thermometer expands first, resulting in the mercury level to go down. After that the mercury in the bulb expands more than the glass bulb, resulting in the subsequent rise of the mercury level.
Why does the substance in the thermometer stem rise up?
The substance in the thermometer (traditionally mercury (Hg)) rises up because of thermal expansion. As the substance heats up, it expands.
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.
