Latent HeatHardQuestion 30858

Question

Pressure cooker cooks faster because:
  1. A
    Water boils at lower temperature
  2. B
    Steam is drier
  3. C
    Higher pressure raises boiling point, enabling higher cooking temperature
    Correct
  4. D
    Latent heat decreases at high pressure

Correct answer

Higher pressure raises boiling point, enabling higher cooking temperature

Explanation

Clausius-Clapeyron: higher pressure → higher boiling point. Food cooks at above 100°C, so cooking is faster.
