Answer:

Freezing and melting. Freezing is the change that occurs when a liquid changes into a solid as the temperature decreases. Melting is the opposite change, from a solid to a liquid as the temperature increases. These are both examples of changes in the states of matter of substances.

Answer:

Hey mate! here are some points for u to understand it better the difference between freezing and melting phenomenon....

1.The melting point is the temperature at which a solid is changed into a liquid by applying heat and pressure while the freezing point is the temperature at which a liquid is changed into a solid.

2.While most substances, especially pure substances, have the same melting and freezing points. Some substances, like mixtures and compounds, have lower freezing points than their melting points.

3.The melting point of a substance depends on the standard atmospheric pressure while pressure has a minor effect on the freezing point of a substance.

4.The melting point of a substance is the basis for the determination of its purity and the identification of compounds while the freezing point is not.

5.The melting point of a substance is considered a characteristic property while the freezing point is not.
