Question

Why do solids melt on heating?

Answer 1

Melting is a process that causes a substance to change from a solid to a liquid.
A solid changes to liquid on heating! When we heat a solid then the heat energy changes to kinetic energy of particles of solid! They start vibrating on a faster rate! Due to heat enegy the secondary bonds between the particles break down. After that the particles start seperating away due to which the fluidity increases and the. The state of the material start changing! So on heating the solid changes to liquid!
