  • Work Done by a Gas

    2021 5 13 So it is more correct to define the work as the integrated or summed variable pressure times the change of volume from State 1 to State 2 If we use the symbol S ds for integral then W = S p dV On a graph of pressure versus volume the work is the area under the curve that describes how the state is changed from State 1 to State 2.
