A container with a volume of #8 L# contains a gas with a temperature of #120^o K#. If the temperature of the gas changes to #360 ^o K# without any change in pressure, what must the container's new volume be?
The new volume is 24 L.
This is an isobar transformation (with constant pressure).
In this transformation when the temperature increases, the volume increases. This means that the ratio between volume and temperature is constant.
This law is called Charle's law and mathematically it is expressed as
The ratio between the initial volume and initial temperature is equal to the ratio between the final volume and final temperature.
The initial volume is
