Explanation:
When matter changes from one state to another state, it is called a change of state. Matter can exist in three states - solid, liquid, and gas. The conversion of matter from solid state to liquid state is called melting.

What is melting?
Melting is the process by which matter changes from a solid state to a liquid state. When heat is applied to a solid, the molecules start moving faster and the bonds between them start to break down. This causes the solid to change into a liquid.

Examples of melting:
Some examples of melting are:

- Ice melting into water when it is heated.
- Wax melting when it is heated.
- Chocolate melting when it is heated.

Factors affecting melting:
The factors that affect melting are:

- Temperature: The higher the temperature, the faster the melting process.
- Pressure: Increasing pressure can also affect the melting point of a substance.
- Type of substance: Different substances melt at different temperatures.

Uses of melting:
The process of melting is used in various industries, such as:

- Metallurgy: The process of melting is used to extract metals from ores.
- Food industry: The process of melting is used to melt chocolate, cheese, and other ingredients.
- Glass industry: The process of melting is used to make glass.

Conclusion:
Melting is an important process that occurs when matter changes from a solid state to a liquid state. It is affected by various factors such as temperature, pressure, and the type of substance. The process of melting is used in various industries for different purposes.

Take an ice Cube and take a pan put it on the gas stove and on the gas stove and after some minute you will see that ice is getting into liquid so that's why conversion of solid state to liquid state is called melting
