Definition1/15
specific heat capacity of a substance is defined as the QUANITY OF HEAT REQUIRED to raise the temperature of 1 Kg of the substance through 1K ( kelvin ) .
however it obtained the unit of J/kg/k
The specific heat capacity is the energy required to raise the temperature of 1 kg of material by 1 degree Celsius.
