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?
Options
- A5 R 3
- B3 5 R
- C7 4 R
- DR 4
Correct answer
C. 7 4 R
Step-by-step solution
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
