The heat capacity of air at room temperature and pressure is approximately 21 Jmol-1K-1. a) How much energy is required to raise the temperature of a room dimensions 5.5 m x 6.5 m x 3.0 m by 10C from room temperature (298.15 K) assuming ideal behavior? b) How long will it take a heater rated at 1.5 kW to achieve that increase if 1 W = 1 Js-1 (assuming no loss)?
