Question

Raindrops are spherical in shape because

• A. Spheres have highest surface area and hence least surface tension
• B. Spheres have least surface area and hence least surface tension
• C. Spheres have highest surface area and hence highest surface tension
• D. Spheres have least surface area and hence highest surface tension

Answer 1

The correct option is D Spheres have least surface area and hence highest surface tension

For water and air, force of adhesion is less than the force of cohesion and hence water prefers to stick to itself rather than the air. To achieve this, water takes the shape of spherical droplets to minimize its contact with the glass surface.
