What is the relation between temperature and volume?

Answer 1

Charles' Law states that the temperature and volume of a gas are directly related. Therefore, as the temperature of a gas increases, so will its volume, and as its volume decreases, so will its temperature.

Answer 2

To state this relationship, pressure must be constant. The temperature is directly proportional to the volume, that is, if you double the temperature then the volume is doubled. This relationship is known as Charles' Law.

Answer 3

The relation of volume and temperature for an Ideal Gas is given by Charles

law of gases that states, that for a given amount of gas it's volume varies directly

proportional to his thermodynamic temperature when keeping the gas at a constant pressure.

Let P = constant, then V/T = constant.

This means that if you double the gas thermodynamic temperature [in Kelvin or Rankine degrees], the volume of the gas doubles.

If you cool the gas to half its thermodynamic temperature, the gas volume reduces

by half.

Another way to show this relation is;

Keeping P = constant, V1/T1 = V2/T2

Answer 4

The relation between the temperature (T) and volume (V) of a perfect gas is given by Charles's law, which states that the volume of a gas is proportional to its temperature. Mathematically:

V = c.T

where c is a constant.

Whilst most liquids and solids behave in a similar way, the situation is generally much more complex. Most materials expand when heated, but there are many materials that actually contract with higher temperatures.

In almost all cases, the relationship between temperature and volume is much more complex, often expressed in the form:

V = c0T + c1T2 +c2T3...

where co, c1, c2... are constants for a given material.

Answer 5

For most substances, as the temperature goes down, the volume decreases. The one notable exception is water, which expands as it freezes.

2. In addition to water, Silicon, Bismuth and Gallium all have the curious property of the density decreasing as they approach freezing point.

I know of no scientific use for this behaviour, but there must be a $ in it.

Answer 6

Charles' Law: Temperature and volume are directly related. If one goes up, so does the other (provided that P and n remain constant).

Answer 7

They have a direct relationship

if temperature goes up, the volume goes up

Answer 8

At constant pressure, V1/T1 = V2/T2.
