.10 mol of Argon gas is admitted to an evacuated 50cm cubed container at 20 degrees celsius. The gas then undergoes an isobaric heating to a temperature of 300 degrees celsius. What is the final volume of the gas?

• physics -

The issue here in my mind is the chamber fixed volume or not? I don't know how one evacuates a chamber that can change size. If it is fixed, the volume remains at 50ml.
