Why does the liquid expand in a thermometer when it gets hotter?
The liquid in a thermometer expands when it gets hotter because heat causes the molecules in the liquid to move faster and spread out, leading to an increase in volume. This expansion is what causes the liquid to rise up the tube of the thermometer, indicating a higher 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 thermometer go down when the temp gets cold?
A thermometer measures temperature based on the expansion or contraction of the liquid or metal inside it. When it gets cold, the molecules inside the thermometer contract, causing the liquid or metal to shrink, which in turn results in the reading on the thermometer going down.
What is a thermometer made out of?
a liquid thermometer is made with a glass "shell" and ussually have murcur inside them that dilates when it gets hotter and rises and contracts when its colder and lowers- this has been made by a 12 year old boy
What happens to a thermistor as it gets colder?
As a thermistor gets colder, its resistance increases. This is because the material in the thermistor contracts, reducing the number of charge carriers available for conduction, hence increasing resistance.
What causes the liquid to move in a thermometer?
When the liquid in the thermometer gets warmer it expands.
What burns you as it gets colder?
liquid nitrogen
What happens when a liquid condenses?
I don't think you can condense a liquid, you can evaporate a liquid eg water which turnns into water vapour then when the water vapour gets colder it cools and condenses

What happens when the temperature in a river rises and what happens when it falls?
it gets warmer then it gets colder

Does a solid get warmer or colder when it turns into a liquid?
It gets warmer so it melts into a liquid

What happens when heat is taken from Matter?
it gets colder

What water vapour does when it gets colder?
turns back into liquid water
When air is cooled what happens?
Uhm, it gets colder of course....
