a) On a winter day, a certain house loses 5108 J of heat to the outside (about 500,000 Btu). What is the total change in entropy due to this heat transfer alone, assuming an average indoor temperature of 22 C and an average outdoor temperature of 4 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? Only answer part (a) for the total change in entropy for the house + outside. (house decreases in entropy but outside gains more, for a net positive change)
