# A container with a volume of #6 L# contains a gas with a temperature of #150^o K#. If the temperature of the gas changes to #570 ^o K# without any change in pressure, what must the container's new volume be?

Use Charles' Law: volume is directly proportional to absolute temperature at a fixed mass and constant pressure.

#### Explanation:

Charles' Law as stated above can be expressed as V =KT.

Volume is directly proportional to absolute temperature at a fixed mass (number of moles) and constant pressure. In this formula, K is just a proportionality constant. Absolute temperature means all temperatures must be expressed in Kelvin.

Another way to write this law is:

Let

Cross multiply.
