Problem 47PE

(a) On a winter day, a certain house loses 5.00×108 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 21.0º C and an average outdoor temperature of 5.00º 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?

Step-by-Step Solution:
Step 1 of 3

Solution  47PE

  the total change in the entropy is  9.78x104 J/KIn order to gain more energy, we must generate it from things within the house, like a heat...
