A 4-m x 5-m x 6-m room is to be heated by a baseboard resistance heater. It is desired that the resistance heater be able to raise the air temperature in the room from 7°C to 23°C within 15 minutes. Assuming that the room loses heat through the walls at a rate of 1500 kJ/h and that the ambient pressure is 100 kPa, determine the power of the resistance heater. Assume constant specific heats at room temperature.
