(N/A) The latent heat $(L)$ is defined as the amount of heat energy required to change the state of a unit mass of a substance without changing its temperature. It is given by the formula $L = Q/m$,where $Q$ is the heat energy and $m$ is the mass.
$1$. Unit: The $SI$ unit of latent heat is $J/kg$ (joule per kilogram).
$2$. Dimensional Formula: Since $Q$ has dimensions $[M L^2 T^{-2}]$ and $m$ has dimensions $[M]$,the dimensional formula for latent heat is $[M^0 L^2 T^{-2}]$.
$3$. Dependency: The value of latent heat depends on the nature of the substance and the temperature/pressure at which the phase change occurs.
