Define specific heat and heat capacity.

Solution

Specific heat:
Specific heat is the quantity of heat required to raise the unit temperature of unit mass of the substance by 1-degree celsius of temperature. 

If dH heat is required to raise the temperature of m gram of substance through dT degree Celsius, then
 
                         dH = mS(dT)
where,
 S is the specific heat of the substance.
Mathematically it is given by, 
therefore space space space space space straight S equals 1 over straight m open parentheses dH over dT close parentheses
Unit of specific heat is cal/g/K or J/kg/K.
