P-V diagram of a diatomic gas is a straightline passing through origin

1.	P-V diagram of a diatomic gas is a straightline passing through origin. What is the molar heat capacity of the gas in the process
Answer» Solution :P-V DIAGRAM of the gas is a straight line passing through origin. HENCE, `P prop V or PV^(-1)=` constant Molar heat capacity in the process `PV^(N)=` constant is `C=(R )/(gamma-1) +(R )/(1-n)` Here, `gamma=1.4` (for diatomic gas) & n = -1 `:.C =(R )/(1.4-1) +(R )/(1+1)or C = 3R`
