Last updated on December 28th, 2021 at 02:10 pm

Here, we will find out the dimensional formula of Surface energy per unit area. This term is related to surface tension. This surface energy relates to the surface of a liquid.

The formula of Surface energy per unit area = Surface energy /total area

The dimensional formula of energy = The dimensional formula of work = [ML²T^–2] [see here how to find the dimensional formula of work ]

The dimension of area = [L²]

Hence, the Dimensional formula of Surface energy per unit area
= The dimensional formula of work / The dimensional formula of area
= [ML²T^–2] /[ L² ]
= [ML⁰T^–2]

Dimensional formula of Surface energy per unit area = [ML⁰T^–2]

Note: Dimensional formula of Surface energy per unit area = Dimensional formula of Surface tension
