The tendency of a liquid drop to contract and occupy minimum area is due to:
✓ Correct answer: a) surface tension
ExplanationSurface tension is the force that acts on the surface of a liquid, causing it to contract and minimize its surface area.This effect occurs because molecules at the surface of the liquid experience a net inward force due to the attractive forces between the molecules.As a result, the liquid tends to form shapes that have the least surface area, such as spherical droplets.This tendency to minimize surface area is why liquid droplets form spherical shapes in free space, as a sphere has the smallest surface area for a given volume.236
