Melting: Changing a Solid into a Liquid on Heating

Melting is the process of changing a solid into a liquid by heating it. It occurs when a solid substance absorbs heat energy and the particles in the solid start to vibrate faster and faster. They eventually absorb enough energy to overcome the forces that hold them together, and the solid turns into a liquid.

Examples of Melting

Melting is a common process that occurs in our everyday lives. Here are some examples of melting:

- Ice melting into water when it is left out of the freezer
- Chocolate melting in your mouth or on a warm surface
- Wax melting when it is heated up in a candle

Melting Point

Every substance has a specific temperature at which it melts, which is known as its melting point. The melting point of a substance is the temperature at which it changes from a solid to a liquid. Different substances have different melting points, depending on their chemical structure and properties.

Uses of Melting

Melting has many practical uses in our daily lives. Here are some examples:

- Melting is used to make candles and wax products
- Melting is used in the production of metals and alloys
- Melting is used in cooking and baking, such as melting butter or chocolate

Conclusion

Melting is the process of changing a solid into a liquid by heating it. It occurs when a solid absorbs heat energy and the particles in the solid start to vibrate faster and faster. Melting has many practical uses in our daily lives and is a common process that occurs in nature and in industry.
