Before the quarantine, 23 candidates for passing PHY136 took the final exam, all in the same room. Each candidate had a power output of about 185W. At the start of the test, the temperature of the room was 66 ⁰F, and the room had dimensions of 21 ft by 45 ft by 11 ft. What was the temperature in the room at the end of the 75 minutes if all the energy remained in the air in the room and none was added by an outside source? The specific heat of air is 837 J/(kg ⁰C), and its density is about 1.3x10-3 g/cm3 .
