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

`Delta Q = Delta u + Delta w`
Since container is nonconducting, therefore
`Delta Q = 0 Delta u + Delta w`
`implies Delta W = - Delta u = - n (f)/(2) R Delta T`
`= - 2 xx (5)/(2) R (400 - 300)`
`= - 5 xx 8.314 xx 100 J = - 5 xx 831.4 J xx - 4175 J`
