Answer 1

$\bold{latent \: heat : }$

The amount of heat required to change the state of matter without changing temperature is called Latent heat.

• Latent heat of fusion: The heat required to convert 1 kg solid into the liquid state is called latent heat of fusion.

value = 3.34 × 10⁵

• Latent heat of vaporization: The heat required to convert 1 kg liquid into vapour state is called latent heat of vaporization.

Value = 22.5 × 10⁵

Answer 2

While ice melts, it remains at 0 °C (32 °F), and the liquid water that is formed with the latent heat of fusion is also at 0 °C. The heat of fusion for water at 0 °C is approximately 334 joules (79.7 calories) per gram, and the heat of vaporization at 100 °C is about 2,230 joules (533 calories) per gram.
