Question

A class of 14 students taking an exam has a power output per student of about 200 W. Assume the initial temperature of the room is 20°C and that its dimensions are 6.9 m by 18.0 m by 3.0 m. What is the temperature of the room at the end of 1.0 h if all the energy remains in the air in the room and none is added by an outside source? The specific heat of air is 1.01 ✕ 103 J/kg · °C, and its density is about 1.2 10-3 g/cm3.
