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
Does matter expand in heat or in the cold?
MOST matter expands as it gets hotter.
Why does a thermometer rise up when its hot?
Usually when a thing gets hot, it expands. The liquid in the thermometer gets hot, and expands, so it takes up more room in the tube.
Do metal expand when it gets cold?
No. Most materials expand when they get hotter. A notable exception is water between 0 and 4 degrees centigrade.No. Most materials expand when they get hotter.

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 in thermometer go up the tube when it gets hotter?
Heat causes mercury in the thermometer to expand, where as when it is cooled, it contracts.
What happen to the liquid in a thermometer when it gets warm?
The liquid expand from heat. We use these expansion to indicate temperature. Common thermometer liquid is Mercury and alcohol.
How does the temperature increase on a thermometer?
it gets hotter
What happened to the temperature of a liquid as it evaporates?
It gets hotter
How a liquid thermometer works using thermal expansions?
In the right conditions and circumstances all liquids will expand
What causes the liquid to move in a thermometer?
When the liquid in the thermometer gets warmer it expands.

Why mercury is used in thermometer for indication?
Because it is just a standardised and easy way of making thermometers. You could use any substance, the pricible is the same: A substance will expand the hotter it gets. Mercury just expands a lot more than most elements and so is easier to make a thermometer.
Why does the liquid level rise in a theremometer when the temperature is higher?
When the liquid is heated (by the environment), the particles in the liquid have more energy, and start moving around more, which causes the liquid to expand and take up more room. Conversely, in cold temperatures, the particles do not have as much energy, and do not move as much, so the liquid contracts.

How mercury functions in a thermometer?
Mercury, like most substances, expands when it gets hotter and contracts when it gets colder. A mercury thermometer is designed so that the volume of the mercury can be accurately observed, as the mercury rises or falls in a marked column.
