A monotomic ideal gas undergoes a process in which the ratio of p to V at any instant is constant and equals to 1. what is the molar heat capacity of the gas?

A

`(4R)/2`

B

`(3R)/2`

C

`(5R)/2`

D

0

Text Solution

Verified by Experts

The correct Answer is:
A
Molar heat capacity
`C = C_(v) + R/(1-lambda)` when `PV^(lambda)` = constant
`C_(v)= (3//2)R` for monoatomic gas .
Given that P/V = 1
`PV^(-1)=1 `
So `lambda= - 1 `
`C = 3/2 R +R/(1-(-1)) rArr C = (4R)/2 ` .
