System gives off 196 kj of heat to the surroundings and the surrounding do 4.20x 10^2 kj of work on the system. What is the change in internal energy of the system.

A5 mole sample of liquid acetone is converted to a gas at 75.0°c. if 628 j are required to raise the temperature of the liquid to the boiling point, 15.600 kj are required to evaporate the liquid, and 712 j are required to raise the final temperature to 75.0°c, what is the total energy required for the conversion?
