Two moles of a diatomic gas at 300 K are kept in a nonconducting container enclosed by a piston . Gas is now compressed to increase the temperature from 300 K to 400 K. Find word done by the gas

Text Solution

Verified by Experts

`DeltaQ = DeltaU +W`
Since container is non conduting therefore
`DeltaQ = 0 =DeltaU +W`
`rArr W =- DeltaU =- n(f)/(2)R DeltaT =- 2 xx (3)/(2) (400-300)`
`=-3 xx (25)/(3) xx 100J =- 2500J`
