Question

One mole of an ideal diatomic gas whose pressure
changes with volume as P = alphaV, where alpha is
constant. The molar heat capacity of the gas is
(1) R
(2) 2R
(3) 3R
(4) 4R​

Answer 1

Answer:

The molar heat capacity of the gas is C = 3R

Explanation:

As we know that molar heat capacity of polytropic process is given as

where process is given as

$PV^N = C$

here we have

$C = C_v - \frac{R}{N-1}$

now here we know that

$P = \alpha V$

$PV^{-1} = \alpha$

so we have

$C = C_v - \frac{R}{-1 -1}$

As we know that for diatomic gas

$C_v = \frac{5R}{2}$

so we have

$C = \frac{5R}{2} + \frac{R}{2}$

$C = 3R$
