Work done on a ideal gas in a cylinder when it is compressed by an external pressure in a single step is shown below: Which of the following graphs will show the work done on the gas?

Correct answer

Step-by-step solution

The pressure is constant and equal to P e x Also the process is a single step Therefore, it is a straight line parallel to volume axis and has a value of P e x Also, work done = P ex ⋅ Δ V = Area under theP−Vcurve.
