Question

4. What happens when solid is heated?
Explain on the basis of kinetic
theory of matter.​

Answer 1

Answer:

When a solid is heated the particles gain energy and start to vibrate faster and faster. ... The particles in the liquid are the same as in the solid but they have more energy. To melt a solid energy is required to overcome the attractions between the particles and allow them to pull them apart.

Answer 2

Answer:

$\color{green}{Answer}$

When a solid is heated the particles gain energy and start to vibrate faster and faster. Initially the structure is gradually weakened which has the effect of expanding the solid. Further heating provides more energy until the particles start to break free of the structure.
