Which of the following is incorrect ?

Options

A. A real gas behaves like ideal gas over a wide range of pressure `(~ 100 atm)` at Boyle point
B. A real gas behaves like an ideal gas over a wide range of pressure `(~100 atm)` at critical temperature of the gas
C. `((del U)/(del V))_(T) = 0` for an ideal gas
D. `((del U)/(del V))_(T) = (a)/(V^(2))` for a real gas obeying van der Waals' equation

Answer

C

Explanation

A real gas cannot behave like ideal gas at critical temperature
