If the P-V diagram of a diatomic gas is ...

If the P-V diagram of a diatomic gas is plotted, it is a straight line passing through the origin. The molar heat capacity of the gas in the process is IR, where I is an integer. Find the value of I.

Verified by Experts

The correct Answer is:
3
`P prop V`, since the graph is a straight line. `PV^(-1)` = constant
`C = R/((gamma -1)) + R/((1-x))`
But here, `gamma = 1.4` and ` x = -1," So I = 3"`
