A gas is confined to a cylinder with a moveable piston to

A gas is confined to a cylinder with a moveable piston (to allow the gas to expand or contract) under a pressure of 1 atmosphere. When the temperature of the gas is increased, 850 J of heat is added, and the gas expands, doing 150 J of work on the surroundings. What are the values of ΔH and ΔE in this process?
