The S.I. unit of specific heat capacity is

Options

A. `"J kg"^(-1) ""^(@)C^(-1)`
B. `"cal g"^(-1)""^(@)C^(-1)`
C. `"J kg"^(-1) K^(-1)`
D. All of the above

Answer

C

Explanation

Amount of heat energy required to raise the temperature of unit mass of a substance through `1^@C` is called specific heat capacity.
`therefore` Its SI unit is `"J kg"^(-1) K^(-1)`
