Suppose you try to cool your home in the summer by letting heat flow from your house to your neighbor's home. You will
A) Not get far, because of the zeroth law of thermodynamics
B) Not get far, because of the first law of thermodynamics
C) Have a cool house in a couple hours
D) Have a warmer house in a couple hours

The zeroth law of thermodynamics states that if two systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium with each other. This principle implies that heat flow is driven by temperature differences, and without a temperature difference between your house and your neighbor's, there would be no spontaneous flow of heat from one to the other. Therefore, trying to cool your house by letting heat flow into your neighbor's house (assuming both houses were initially at the same temperature) would not be effective.
