Question

The unit of latent heat is equivalent to the unit of:

• A. ${\left(force\right)}^2$
• B. ${\left(acceleration\right)}^2$
• C. ${\left(velocity\right)}^2$
• D. ${\left(density\right)}^2$

Answer 1

The correct option is C ${\left(velocity\right)}^2$

$Latentheat=\frac{Energy}{Mass}=L^2{T}^{-2}$
${\left(force\right)}^2={\left(M{L}^1{T}^{-2}\right)}^2$
$(ac{c}^n{)}^2=(L{T}^{-2}{)}^2$
$(velocity{)}^2=(L{T}^{-1}{)}^2=L^2{T}^{-2}$
$(density{)}^2=({ML}^{-3}{)}^2=M^2{L}^{-6}$

Hence, option C is correct.
