Question

The rate of heat leaking into a house from the warmer outdoors is given by A(TH – TC) where TC and TH denote the indoor and outdoor temperatures, respectively, and A is a constant.

If the outdoor temperature is 32°C, what will be the ratio of the power required to maintain an indoor temperature of 21°C to that required to maintain an indoor temperature of 25°. Assume the air conditioning system operates at its maximum possible coefficient of performance.
