(a)On a winter day, a certain house loses 5.33 10 ✕8J of heat to the outside. What is the total change in entropy of the universe due to this heat transfer alone, assuming an average indoor temperature of 24.0°C and an average outdoor temperature of 5.05°C?(b)This large change in entropy implies a large amount of energy has become unavailable to do work. Where do we find more energy when such energy is lost to us?
