प्रश्न
Explain why, ice at 0° C is more effective in cooling than water at the same temperature.
उत्तर
Ice at 0°C is more effective in cooling than water at the same temperature, because ice absorbs the latent heat of 3.34 × 105 joules from the substance and cools it effectively. On the other hand, water at the same temperature doesn't take any heat from the substance.
