Question

Solid and liquid coexist at their melting point. Give reason

Answer 1

At the melting point the solid and liquid state are in dynamic equilibrium , i.e, the particles are constantly converting from one form to another at a constant rate . This is why solid and liquid coexist at melting point . The same thing happens at boiling point as well.

Hope you understand the solution!!

Answer 2

Answer:

Melting point is the fixed temperature at which a solid changes into a liquid. A substance exists in the solid-state below its melting point and in liquid state above its melting point hence solids and liquids coexist at the melting point.
