A container with a volume of #6 L# contains a gas with a temperature of #650 K#. If the temperature of the gas changes to #350 K# without any change in pressure, what must the container's new volume be?
You can use Charles' Law for this:
Find your values:
and plug them in:
Divide both sides by
And that's your final answer. The container's new volume must be
Note that if the temperature were in Fahrenheit or Celsius you would have to convert to Rankine or Kelvin, respectively - as Charles' Law only works with an absolute temperature scale. However, since the given temperatures were in Kelvin, no such conversion is necessary.
