Heat capacity


The heat capacity of a system may be defined as “the amount of heat required to raise the temperature of the system through 1oC.”
As the system absorbs heat, it increases the kinetic energy of the atoms and molecules continued in the system. This increased kinetic energy raises the temperature of system.
If ‘q’ calories of the heat is absorbed by system of mass ‘m’ and its temperature rises from T1 to T2. Then heat capacity is given by the expression,
              Heat Capacity =   q / (m*(t2-t1))
