Find the ∆E
a) When 175J of work is done on a system that evolves 50J of heat to the surrounding. b) When a gas absorbs 28kJ of heat and 13kJ of work done on it.
A system absorbs 50J of heat during a transformation. Determine the change in internal energy if the system perform, (a) 15J and (b) 65J of work on the surrounding.
