BIO NMDCAT Biological Importance of Water
nmdcat.online June 27, 2026

The spherical shape of a water droplet in zero gravity is a direct manifestation of

A. Viscosity dominating over all other forces
B. Surface tension minimizing the surface area for a given volume
✓
C. The high density of water pulling it inwards equally
D. The low vapor pressure of water in a vacuum

📝 Explanation

Water molecules experience a net inward pull due to unbalanced cohesive forces at the surface. This surface tension forces the droplet to assume the shape with the smallest possible surface area-to-volume ratio, which is a perfect sphere in the absence of gravity.

📖 Additional Information
