Heat capacity

The amount of energy Q that is needed to heat up1kg of a material about 1K is called specific heat capacity c of a material.

Unity [c ]     1J/kg ⋅ K

The heat capacity of a material results from the product of the specific heat capacity and the mass of the object. It is called C.

Unity [C ]     1J/K

Some examples for the specific heat capacity:

Material	Specific heat capacity (in J/kg ⋅ K)
Iron or steel	450
Luft	1010
Wood	2300
Water	4190
Human body	3470 (on average)
