Specific heat is another physical property of matter.
All matter has a temperature associated with it.
Typicall this energy is supplied by heat. Heat loss or gain by matter is equivalent energy loss or gain. Thus, the specific heat of a gallon of milk is equal to the specific heat of a quart of milk. What this means is that it takes 0.385 Joules of heat to raise 1 gram of copper 1 degree celcius. A simple way of dealing with different masses of matter is to dtermine the heat capacity C as defined above.
