A monoatomic gas undergoes a process in which the pressure ( P ) and the volume ( V ) of the gas are related as P V - 3 = constant. What will be the molar heat capacity of gas for this process?

Question

A monoatomic gas undergoes a process in which the pressure ( P ) and the volume ( V ) of the gas are related as P V - 3 = constant. What will be the molar heat capacity of gas for this process?, 5 R 3, 3 5 R, 7 4 R, R 4

P V - 3 = c o n s t a n t n = - 3 C = R γ - 1 - R n - 1 γ = 5 3 C = R 5 3 - 1 - R - 3 - 1 = 3 R 2 + R 4 = 7 4 R
