Is surface tension a vector ?

Explanation

To determine whether surface tension is a vector quantity, we can follow these steps:

### Step 1: Define Surface Tension
Surface tension (T) is defined as the force per unit length acting along the surface of a liquid. It can also be expressed as the work done per unit change in surface area.

### Step 2: Understand the Components of Surface Tension
- **Work Done (W)**: This is a scalar quantity, as it is the product of force and displacement.
- **Change in Surface Area (ΔA)**: This is also a scalar quantity, as it represents a measure of area.
