Hey there, I built this website for students studying for tough tests. I think everyone should get education for free, so that's why I made this site. But now, the way Google ranks websites changed, and not many people are visiting here. I use money from Google ads to keep this site running, but with less visitors, it's hard to do that anymore. If you like this website and want it to keep going, can you help out? Any support you give would be really appreciated. Thanks a lot for considering it.

Pick out the wrong statement.

A. The values of (∂P/∂V)T and (∂2P/∂V2)T are zero for a real gas at its critical point

B. Heat transferred is equal to the change in the enthalpy of the system, for a constant pressure, non-flow, mechanically reversible process

C. Thermal efficiency of a Carnot engine depends upon the properties of the working fluid besides the source & sink temperatures

D. During a reversible adiabatic process, the entropy of a substance remains constant
