Latent heat: The heat required to change one state of matter into another (solid into a liquid or vapor, or a liquid into a vapor) without in change of temperature.
• The liquid water to be formed when ice melts will be at 0° Celsius.
• Given: Latent heat of melting of ice = 333.6 J/g.
• 1 gm of ice requires 333.6 J heat to melt,
• For 100 gm, it is 33360 Joules.
