A system absorbs 1000 J of heat and does work equivalent to 400 J. Calculate the charnge in internal energy of the system.

Text Solution

Verified by Experts

Heat absorbed by the system , `q = + 1000 J,` Work done by the system, `w =- 350 J`
Change in internal energy ,` Delta U = q + w = 100 + ( - 350) J = 650 J`
Change in internal energy, `Delta U = q + w = 100-0 + (350) J = 650 J`
