One kg of a diatomic gas is at pressure ...

One kg of a diatomic gas is at pressure of `8xx10^4N//m^2`. The density of the gas is `4kg//m^3`. What is the energy of the gas due to its thermal motion?

A

`6 xx 10^(4)J`

B

`7 xx 10^(4)J`

C

`3 xx 10^(4)J`

D

`5 xx 10^(4)J`

Text Solution

Verified by Experts

The correct Answer is:
C
Energy of the diatomic gas `(5)/(2)nRT = (5)/(2)PV = (5)/(2)xx 8 xx 10^(4) xx (1)/(4) = 5 xx 10^(4)J`
