Work done = Pressure * ΔV [ change in volume ]
If ΔV=0, then no work is done
Zero work thermodyanamic process is called ' isochoric process.'
For example if a gas heated in a rigid container: the pressure and temperature
of the gas will increase, but the volume will remain the same.
This is called an isochoric thermodynamic process.
It is actually possible to do work on a system without changing the
volume, as in the case of stirring a liquid
