A class of 11 students taking an exam has a power output per student of 124 W. Assume that the initial temperature of the room is 18.7C and that its dimensions are 6.00 m by 14.5 m by 3.40 m. What is the temperature (in C, do not enter units) of the room at the end of 55.0 min if all the heat remains in the air in the room and none is added by an outside source? The specific heat of air is 832 J/kg*C, and its density is about 1.34E-3g/ cm3.
