Problem 1: A man (the system) walks inside an isolated room for 5 hours and does W=1250JW = 1250 , text{J}W=1250J of work. The internal energy decreases by U=2250JDelta U = -2250 , text{J}U=2250J. Determine the heat QQQ (with sign). Follow-up: If the system instead gains 3000J3000 , text{J}3000J of heat while performing the same…
