A system absorbs 1000 J of heat and does work equivalent to 350 J. Calculate the change in internal energy of the system.

Text Solution

Verified by Experts

Heat absorbed by the system, `q = + 1000J:` Work done by the system, `w =- 350 J`
Change in interanl energy , `Delta U = q + w = 1000 + (-350) J = 650 J`
