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 a liquid thermometer works using thermal expansions?

The liquid contained within he thermometer's tube expands with heat, or contracts with cold. This is shown by the length of liquid in the tubing.


Why does the liquid in thermometer go up the tube when it gets hotter?

The liquid expands and since the only place for it to go is up it starts to fill the tube

Explain how a liquid thermometer measures temperature?

OK basically depending on what thermometer. the glass tube is filled with either alcohol or Mercury. and when it gets hotter, the liquid expands and takes up more space inside the tube. and colder.......the liquid compacts and moves down the tube.....and it's taken years to calabrate the markings on the tube to show the correct reading.


On what principal do most thermometer work?

liquid expands as it gets warmer


Why is water not used as a liquid in a thermometer?

if you put water in a thermometer and it gets hot the water expands and might and burst and when it gets to cold it freezes


Does the mass of liquid change if the volume of it changes?

The only way that the mass can change is if matter is added or taken away. The volume of a liquid can increase if heated, such as the liquid inside of a thermometer. The thermometer is sealed and no liquid gets in or out, so the mass of the liquid is unchanged. But when the temperature goes up, the liquid expands and is forced to go up the thermometer.


Why does the liquid level rise in a theremometer when the temperature is higher?

The liquid in the thermometer's bulb gets heated and, as it does, it expands into the stem.


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.


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.


Why do steal bridges have gaps on them?

The gaps allow the steal to expand as the day gets hotter, and prevent the steal from buckling.

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.


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


When the temperature of a solid is raised?

They usually expand and when the temperature gets high enough, turns to liquid.


Does plastic heat up?

plastic does heat up because the particles in the plastic bag gets hotter the particles expand and turn warm


What does heat do when heated?
