Substances with high heat capacities absorb more heat before changing temperature than substances with low heat capacities. If you have ever heated water in a metal pot on a stove or campfire, you may have noticed that the metal pot heated up much faster than the water. This is because metal has a lower heat capacity than water. A substance with a high heat capacity can absorb and release more heat per degree temperature change than a substance with a low heat capacity. A substance with a low heat capacity can absorb and release less heat per degree temperature change than a substance with a high heat capacity.
H c is the unknown quantity.
No conversions are necessary. Substitute values with correct units into the original equation and solve. Once again, the reason for this is the hydrogen bonding between water molecules. Temperature is a measure of the motion of molecules. As we reviewed earlier, as the temperature of a substance increases so does the motion of its molecules.
