Energy per unit volume

Vedclass · Answer

(C) The dimension of pressure $(P)$ is defined as force per unit area,which is $[M L^{-1} T^{-2}]$.Energy $(E)$ has dimensions $[M L^2 T^{-2}]$.Volume $(V)$ has dimensions $[L^3]$.Therefore,the dimension of energy per unit volume is $\frac{[M L^2 T^{-2}]}{[L^3]} = [M L^{-1} T^{-2}]$.Since the dimensions of pressure and energy per unit volume are identical,the correct option is $C$.

Dimensions of pressure are the same as that of
