Heat Capacity

If you want to heat up a kettle of water, you need to supply energy. The more energy you supply, the larger is the rise in temperature. In fact, we found from experiments that the rise in temperature of an object is directly proportional to energy supplied to it:

where is a constant called the heat capacity of the object. The heat capacity of an object is thus equal to the energy that needs to raise the temperature of the object by 1 . Heat capacity is measured in .
