$A$ thermodynamic process $(B \rightarrow E)$ is shown in the graph below. The work done in this process is equal to the area under the curve. Identify the correct area representing the work done.

Which one among the following is the correct option for the relationship between $C_{P}$ and $C_{V}$ for one mole of an ideal gas?

In thermodynamics,the $P-V$ work done is given by $w = -\int P_{ext} dV$. For a system undergoing a particular process,the work done is $w = -\int \left(\frac{RT}{V - b} - \frac{a}{V^2}\right) dV$. This equation is applicable to a:
