At constant volume 4 mol of an ideal gas...

At constant volume 4 mol of an ideal gas when heated form 300k to 500k changes its internal energy by 500 J . The molar heat capacity at constant volume is ________.

Text Solution

Verified by Experts

The correct Answer is:
6.25
`DeltaU = nC_(v) DeltaT`
`500 = 4 xx C_(v) xx (500 - 300)`
`C_(v) =(5000)/( 4 xx 200) = 6.25 JK^(-1) mol^(-1)`
