hard
The dimensional formula of latent heat is:
A$\left[\mathrm{M}^0 \mathrm{LT}^{-2}\right]$
B$\left[\mathrm{MLT}^{-2}\right]$
C$\left[M^0 L^2 T^{-2}\right]$
D$\left[\mathrm{ML}^2 \mathrm{~T}^{-2}\right]$
(JEE MAIN-2024)
Solution
Latent heat is specific heat
$\Rightarrow \frac{\mathrm{ML}^2 \mathrm{~T}^{-2}}{\mathrm{M}}=\mathrm{M}^0 \mathrm{~L}^2 \mathrm{~T}^{-2}$
$\Rightarrow \frac{\mathrm{ML}^2 \mathrm{~T}^{-2}}{\mathrm{M}}=\mathrm{M}^0 \mathrm{~L}^2 \mathrm{~T}^{-2}$
