Question

What is the dimensional formula for calorie?

Answer 1

Calorie is the unit of energy hence it has dimensional formula same as energy.
M$L^{2}$$T^{-2}$

Answer 2

Answer:

Calorie has the dimensional formula of $\left[\mathrm{ML}^{2} \mathrm{T}^{-2}\right]$

Solution:

The dimensional formula is derived from the fundamental quantities. There are 7 fundamental quantity defined in nature, through which all other quantities are derived.  

Given is the Calorie.

Calories is the unit of energy. Energy is the property of a body of being able to perform any work.

Energy has the formula of $\mathrm{E}=1 / 2 \mathrm{mv}^{2}$

Calorie = Energy

$\text { Calorie } =\frac{1}{2} \mathrm{m} \mathrm{v}^{2}$

$=[\mathrm{M}]\left[\mathrm{LT}^{-1}\right]^{2}$

$=[\mathrm{M}]\left[\mathrm{L}^{2} \mathrm{T}^{-2}\right]$

$\Rightarrow \text { Calorie }=\left[\mathrm{ML}^{2} \mathrm{T}^{-2}\right]$
