Why is ice at 273 K more effective in cooling than water at the same temperature?

लघु उत्तरीय

  • Ice at 273 K has less energy than water (although both are at the same temperature).
  • Water possesses the additional latent heat of fusion. Hence, at 273 K, ice is more effective in cooling than water.
