What is specific heat? Write its equation and unit,and on what does it depend?

(N/A) Specific heat capacity is defined as the amount of heat energy required to change the temperature of a unit mass of a substance by one unit (degree).
If $\Delta Q$ is the amount of heat absorbed or rejected by a substance of mass $m$ undergoing a temperature change $\Delta T$,then the specific heat capacity $s$ is given by:
$s = \frac{\Delta Q}{m \Delta T}$
Rearranging this,we get the equation: $\Delta Q = m s \Delta T$.
Specific heat capacity is a characteristic property of a substance. It depends on the nature of the substance and its temperature.
The $SI$ unit of specific heat capacity is $J \ kg^{-1} \ K^{-1}$.
The dimensional formula is $[M^0 L^2 T^{-2} K^{-1}]$.
