Question

Define Fusion

Answer 1

Fusion:

• The process by which a substance changes from a solid-state to a liquid state is called melting or fusion.
• This change occurs on heating a solid because the particles of the solid gain energy and start vibrating more vigorously.
• A point is reached where particles gain enough energy to overcome the force of attraction and they start moving.
• Hence, by reducing the intermolecular force of attraction, solid changes into a liquid.
