Dimensional Formula of Heat Energy
The dimensional formula of Heat Energy is given by,
[M1 L2 T-2]
- M = Mass
- L = Length
- T = Time
Energy is the ability to do work.
∴ dimensional formula of Energy = dimensional formula of Work
Work (W) = Force (F) × Displacement . . . . . (1)
Since, F = M × a = M × [M0 L1 T-2]
∴ The dimensions of Force (F) = M1 L1 T-2 . . . . (2)
On substituting equation (2) in equation (1) we get,
Work = [M1 L1 T-2] × [M0 L1 T0] = [M1 L2 T-2].
Therefore, heat energy is dimensionally represented as [M1 L2 T-2].
