If we will take the example of ice ,a solid so when melting or fusion takes place ice convert to water a liquid

Change in State of Matter during the Fusion Process

During the fusion process, the state of matter changes from solid to liquid. This is because fusion is the process of converting a solid substance into a liquid state by supplying sufficient heat energy.

Explanation:

1. Fusion Process
- Fusion is a physical change in which a substance changes from one state of matter to another due to the addition of heat energy.
- It typically involves changing a solid substance into a liquid state.
- Fusion is the opposite process of freezing, where a liquid substance transforms into a solid state.

2. Solid to Liquid Transformation
- In the fusion process, a solid substance receives heat energy, causing the particles within the substance to gain kinetic energy and vibrate more rapidly.
- As the heat energy continues to be supplied, the particles gain enough energy to overcome the attractive forces holding them together in a fixed arrangement.
- As a result, the particles start to move more freely, transitioning from a fixed position in the solid state to a more fluid-like arrangement in the liquid state.
- This change in particle movement and arrangement leads to the transformation of a solid substance into a liquid state.

3. Examples of Fusion
- One common example of fusion is the melting of ice. When heat is applied to ice, it absorbs the energy and undergoes fusion, transforming into liquid water.
- Another example is the melting of a candle wax. When a candle is lit, the heat from the flame causes the solid wax to melt and become a liquid, allowing it to be easily burned.

4. Significance of Fusion
- The fusion process is essential in various applications, such as cooking, where solid ingredients are transformed into liquid or semi-liquid states to prepare different dishes.
- It is also crucial in industrial processes that involve the melting of metals, glass, and other solid materials to shape them into desired forms.

In conclusion, during the fusion process, the state of matter changes from solid to liquid. This transformation occurs when a solid substance receives sufficient heat energy, causing the particles to gain kinetic energy and move from a fixed position to a more fluid-like arrangement.
