The higher the specific heat capacity, the more energy is required to heat a given substance. This would also mean that w<u>ith a higher specific heat capacity, a substance would be able to retain more heat</u>.

With the above statements in mind, water would be the best choice, because it would retain more heat than the other substances once it reaches 100 °C, and in turn water would emit the most heat while it cools.
