Show dimensionally that the pressure is given by (i) energy per unit volume (ii) force per unit area.

Explanation

To show dimensionally that pressure can be expressed as (i) energy per unit volume and (ii) force per unit area, we will follow these steps:

### Step 1: Understanding the Dimension of Pressure
Pressure (P) is defined as force (F) applied per unit area (A). The dimension of pressure can be expressed as:
\[ [P] = \frac{[F]}{[A]} \]
