This liquid is sometimes colored alcohol but can also be a metallic liquid called Mercury. Both mercury and alcohol grow bigger (expand) when heated and smaller (contract) when cooled. Inside the glass tube of a thermometer, the liquid has no place to go but up when the temperature is hot and down when the temperature is cold. Its the process of expansion and contraction

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 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 doesn't the liquid in the thermometer move when you turn it upside down?
Because it doesn't.
Why should liquid waste not be dumped into the sink?
Liquid wastes should not be dumped down a sink because they can cause back-up. This liquid waste could also break pipes.
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
Which device has a liquid in glass components?
thermometer
What is the importance of thermometric liquids?
Thermometric liquid is the liquid found in the thermometer that help in the up and down movement of the temperature.
How does the liquid in a thermometer move up and down?
When the liquid in the thermometer gets warmer it expands. This means its volume increases. The only place for the extra volume to go is up the tube, so the level of liquid rises. When the liquid gets colder it contracts (reduces in volume) so it moves back down the tube. See http://www.energyquest.ca.gov/how_it_works/thermometer.html
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.
What is the liquid in the ball of the thermometer?
the liguid inside the thermometer is Mercury.
