P-V diagram of a diatomic gas is a straight line passing through origin. What is the molar heat capacity of the gas in the process

Text Solution

Verified by Experts

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`
