Define spectific heat capacity and give its unit .

Explanation

Specific heat capacity of substance is defined as the amount of heat energy required to raise temperature of 1kg of a substance by 1 kelvin or `1^@C`
`Delta Q = ms Delta T`
therefore `s = 1/m ((Delta Q)/(Delta T))`
The SI unit for specific heat capacity is `Jkg^(-1) K^(-1)`
