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

The property of water that is most directly responsible for the “cooling effect” felt when a volatile solvent like rubbing alcohol (isopropanol) is placed on the skin is its

A. High specific heat
B. High heat of vaporization
✓
C. High surface tension
D. High dielectric constant

📝 Explanation

The solvent evaporates quickly. This phase change from liquid to vapor requires the absorption of its latent heat of vaporization. This heat is drawn from the skin, causing a rapid and intense cooling sensation, even more pronounced than with water due to its higher volatility.

📖 Additional Information

  • High specific heat
  • High heat of vaporization
  • High surface tension
  • High dielectric constant
