An accountant in charge of reducing expenditures for a local company thinks they can save considerable money on fuel costs by lowering the room temperature of the building for daily use. in the morning, the interior temperature is typically 47.6 ∘f, and the thermostat is typically set for 72.4 ∘f. the accountant proposes to lower the thermostat to 61.5 ∘f. currently, the building measures 23.5 ft×54.9 ft×14.5 ft. how much heat will be saved each morning by changing the building to the new operating temperature of 61.5 ∘f instead of 72.4 ∘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 the answer as a positive quantity.
