Latent HeatHardQuestion 30852

Question

Steam at 100°C is more dangerous than water at 100°C because:
  1. A
    Steam is faster
  2. B
    Steam releases latent heat on condensation in addition to cooling
    Correct
  3. C
    Steam is at higher pressure
  4. D
    Steam has lower density

Correct answer

Steam releases latent heat on condensation in addition to cooling

Explanation

Steam condenses on skin releasing ~2260 J/g, causing much more thermal damage than equal mass of water cooling from 100°C.
