Answer 2

$\huge \underline \frak \red{answer}$

Specific Heat Capacity:-

It is defined as amount of heat per unit mass absorbed or rejected by substance to change its temperature by 1unit.

$ន = \frac{ន}м {} - \frac{1}{ᴍ} \: \frac{Δϙ}{Δᴛ} \\ \\ = \frac{ᴊ}{ᴋɢ} \\ = ᴊ \: ᴋ {ɢ}^{ - 1} \: {ᴋ}^{ - 1}$

Molar specific Heat :-

The amount of heat per unit mole absorbs or rejected from substance to change its temperature by 1 unit.

$ᴄ = \frac{1}{μ} \: \frac{Δϙ}{Δᴛ}$

SI Unit of Molar specific heat is

$ᴊ \: mo {l}^{ - 1}$
