Question
On a trip, you notice that a 3.50-kg bag of ice lasts an average of one day in your cooler. What is the average power in watts entering the ice if it starts at $0^\circ\textrm{C}$ and completely melts to $0^\circ\textrm{C}$ water in exactly one day? 1 watt = 1 joule / second (1W = 1 J/s).

$13.5 \textrm{ W}$
