A piston in a heat engine does 600 J of work, and 1,700 J of heat are added to the system. Determine The change in internal energy and explain how this example demonstrates the conservation of energy. Enter your answer in the space provided

Answer 1

Q-W=change in internal energy,closed system

1700-600=900j
this demonstrates the conservation energy as there is energy is no destroyed,instead energy is converted from one form to another and in this case the leftover energy of the system is the increase in internal energy of the system
