It doesn't 'move' exactly, it expands. Originally Mercury (a metal in a liquid state at room temperature) was used in thermometers; as the the temperature increases the mercury (or other liquid) expands, taking up more of the volume within the thermometer, causing the level to rise. Thermometers are calibrated to allow the temperature to be measured based on how much expansion has taken place.
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.
They expand causing them to move in the only direction available, up the thermometer.
what do they use for the liquid in glass ball thermometer
In a thermometer is a liquid metal called Mercury, so the liquid expands when it is heated up.
the temparature of the liquid must be read while the thermometer is in the liquid.since the level of mercury drops as soon as the thermometer is taken out of the liquid ,therefore no need of the kink in thermometer.
When the liquid in the thermometer gets warmer it expands.

Because it doesn't.
No, heating a liquid makes it's particles move farther apart (makes the liquid expand). This is most readily observed in an old glass thermometer. As your temperature goes up (as you heat the liquid in the thermometer), the liquid inside expands and travels up the thermometer.
Mercury the liquid inside thermometer is mercury.. but it is called thermometric liquid.

thermometer
In a thermometer is a liquid metal called Mercury, so the liquid expands when it is heated up.
the liguid inside the thermometer is Mercury.
This depends on the thermometer model.
the temparature of the liquid must be read while the thermometer is in the liquid.since the level of mercury drops as soon as the thermometer is taken out of the liquid ,therefore no need of the kink in thermometer.
