Early Monday morning, the temperature in the lecture hall has fallen to 42°F, the same as the temperature outside At 7:00 A.M., the janitor turns on the furnace with the thermostat set at 70°F. The time constant for the building is 1 1 1 = 2 hr and that for the building along with its heating system is K = hr. Assuming that the outside temperatu K₁ 2 remains constant, what will be the temperature inside the lecture hall at 8:00 A.M.? When will the temperature insic the hall reach 69°F? .... At 8:00 A.M., the temperature inside the lecture hall will be about F (Round to the nearest tenth as needed.)
