Heat capacity is a measurement of how much energy is required to increase the temperature of a substance.

A substance with a high heat capacity can hold a lot of heat before its temperature increases.

Another way to think about heat capacity is to say that a substance with a high heat capacity will heat up slower than a substance with low heat capacity.

Aluminum

Heat capacity: 0.900 Copper

Heat capacity: 0.385

Which will heat up faster: copper or aluminum?

Answ

erDo you think land or water has a higher heat capacity? 

In other words, which will take longer to heat up?

Water has a much higher heat capacity than land. It warms up much slower than land.

Heat Capacity of WaterThink about the beach on a hot, summer day. You often have to run across the sand so that you don't burn your feet. The ocean, however, feels much cooler.

Which has a higher heat capacity: water or land? Click below to check your answer.
