Question

energy density and pressure have the same dimensions. comment

Answer 1

Answer: Yes the dimension of Pressure and Energy density are equal.

Explanation:

This is as follows:-

Dimension of pressure is [M L^-1 T^-2]-----------(i)

and,

Dimension of energy density is simply (energy/unit volume)

i.e, Dimension of energy density is

= [M L^2 T^-2] / [L^3]

=[M L^-1 T^-2]-----------------(ii)

From (i) and (ii), they are dimensionally equal.

Hope this helps!!!
