Solid elements are rigid elements. For example an element iron is in solid form. You can touch it and it’s hard.

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