In winter, an electric heater uses a certain amount of electrical energy to heat a room to 20oC. In summer, an air conditioner uses the same amount of electrical energy to cool the room to 20oC. Is the change in internal energy of the heater larger, smaller, or the same as that of the air conditioner? Explain.
