Solution
Melting is the process of conversion of a solid to liquid by heating.
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!
The temperature at which the solid melts is called 'melting point'.
The value of melting point varies from solid to solid.
You will come to study more about this in Class 11 chapter 'States of Matter'
