The dimensional formula of latent heat is :

The dimensional formula of latent heat is :
  1. $\left[\mathrm{ML}^2 \mathrm{~T}^{-2}\right]$
  2. $\left[\mathrm{M}^0 \mathrm{~L}^2 \mathrm{~T}^{-2}\right]$
  3. $\left[\mathrm{MLT}^{-2}\right]$
  4. $\left[\mathrm{M}^{\circ} \mathrm{LT}^{-2}\right]$

Solution

Latent heat is specific heat $\Rightarrow \frac{\mathrm{ML}^2 \mathrm{~T}^{-2}}{\mathrm{M}}=\mathrm{M}^0 \mathrm{~L}^2 \mathrm{~T}^{-2}$
