Question

The SI unit of specific latent heat is

• A. $Jk{g}^{-1}{K}^{-1}$
• B. $J^0{K}^{-1}$
• C. $Jk{g}^{-1}$
• D. $Jkg{K}^{-1}$

Answer 1

Answer: (C)

$Jk{g}^{-1}$

The specific latent heat of a substance is the quantity of heat energy required to change the state of a unit mass of a substance.

$E_L=ml$

here $E_L$ is the heat transferred, in joules,m is the mass, in kilograms, and l is the latent heat in joules per kilogram.

The SI unit for specific latent heat is $J{kg}^{-1}$.
