I liked this problem because it's something you can use to talk about money savings w/ other people. Just making sure everything was done right though. 1. The problem statement, all variables and given/known data the interior temperature of the room is typically 34.6°F ( the thermostat is typically set for 70.7°F. you propose to lower the thermostat to 60.1°F. Currently the building measures 23.5 × 34.5 × 14.5 feet How much heat will be saved each morning by bringing the building up to the new operating temperature of 60.1°F instead of 70.7°F? Ignore heat and air losses to the outside and consider air an ideal diatomic gas. Assume that in the morning the pressure in the room is atmospheric. Express your answer as a positive quantity. ---- part 2: electricity rate is $6.56 per kilowatt-hour. How much money (in dollars) is saved each morning by only heating the room to 60.1F? 2. Relevant equations diatomic gas: C_v = (5/2) R R = 8.3144621 J/ mol*K 3. The attempt at a solution edit: found out both of my answers were wrong.
