Why does the thermometer go down when cooled?
The cold reduces the temperature in the liquid inside the thermometer bulb. Most substances contract when their temperature drops so the liquid in the bulb occupies less space. this causes the column of liquid outside the bulb to become smaller.
What is the mass and capacity in liquid in a thermometer?
This depends on the thermometer model.
What was the first liquid used in a thermometer?
The first thermometer was a tube filled with water and air.
What effect does the use of an uncalibrated thermometer have on the boiling point of a liquid?
The thermometer's reading of the point the liquid boils may not be accurate.
What liquid metal was commonly used in thermometer?
We still use colored alcohol for our liquid in everyday thermometers.
How does a glass thermometer works?
As the liquid in the thermometer is heated it expands, and the only way the expanding liquid can go is upward. As the liquid in the thermometer cools, it will contract, and the liquid will fall back down into the resevoir, causing the column of liquid to move downward.
What are the two substances used in a liquid column thermometer?
iodine and mercury
What is linearity of a thermometer?
Within the thermometer's range of operation, a given temperature difference will result in the same expansion in the column of the thermometric liquid.
What is a thin glass tube with a bulb on one end that usually contains a liquid usually mercury or colored alcohol?
This could describe a thermometer. The only thing missing is the graduations. That way the height of the column can be associated with a specific temperature, the one that caused the column to be as high as it is.
Why does the thermometer go down when cooled?

When a cold alcohol thermometer is placed in a hot liquid, the column of alcohol goes downslightly before going up. Explain why?
because
What is the liquid in thermometer's called?
Mercury the liquid inside thermometer is mercury.. but it is called thermometric liquid.
What causes the liquid to move in a thermometer?
When the liquid in the thermometer gets warmer it expands.
What is liquid-in-glass thermometer?
what do they use for the liquid in glass ball thermometer
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.
Which device has a liquid in glass components?
thermometer
Why does the liquid expand in a thermometer when it gets hotter?
In a thermometer is a liquid metal called Mercury, so the liquid expands when it is heated up.
