Question

Define latent heat of Fusion. Why do we feel cool when we touch a piece of ice?​

Answer 1

Answer:

Hi good morning dear how are u hope u are all right have a sweet day

Explanation:

Heat always travel from higher energy level to lower energy level. The temperature of ice is very low and its energy is also low as compared to our body. So, when we touch ice the heat starts flowing from our body to ice so because we are losing heat energy it feels cold.

Answer 2

Answer:

The enthalpy of fusion of a substance, also known as (latent) heat of fusion is the change in its enthalpy resulting from providing energy, typically heat, to a specific quantity of the substance to change its state from a solid to a liquid, at constant pressure.

• Heat always travel from higher energy level to lower energy level. The temperature of ice is very low and its energy is also low as compared to our body. So, when we touch ice the heat starts flowing from our body to ice so because we are losing heat energy it feels cold.
