What are the values of `w and DeltaE`, when a system absorbs 250J  of heat by expanding from 1 lit to 10 lit against 0.5 atm pressure and at constant temperature.

Text Solution

Verified by Experts

`DeltaE-q=w=-PDeltaV=-0.5(10-1)=-4.5lit-atm`
but, one litre-atm of energy is equal to 101 joules
Work done, `w=-4.5xx101J=-454.5J`
Change in internal energy, `DeltaE=q-w=250-454.5=-204.5J`
