Define spectific heat capacity and give its unit .

Explanation

Specific heat capacity of a substance is defined as the amount of heat energy required to raise the temperature of 1 kg of a substance by 1 kelvin or ` 1^(@)C`
` Delta Q = m s Delta T`
Therefore
` s = 1/m (( Delta Q)/(Delta T))`
where s is known as specific heat capacity of a substance and its value depends only on the nature of the substance not amount of substance .
` DeltaQ ` = Amount of heat energy , ` Delta ` T = Change in temperature , m= Mass of the sustance
The SI unit for spectific heat capcatiy is ` J kg^(-1) K^(-1)`
