Question

When heat is supplied to matter, the ___________ of its molecules increases and they start vibrating vigorously.

Answer 1

1. The process of transfer of heat from the body of a higher temperature to the body of a lower temperature when two bodies are in contact with each other is called conduction.
2. When heat is transferred to the solid, its molecules gain energy and they began to vibrate about their fixed position.
3. The vibrating molecules collide with each other and hence, the energy gets transferred to the neighbouring molecules.
4. The neighbouring molecules hence acquire more kinetic energy.
5. The increased kinetic energy leads to a rise in temperature and in this way the heat gets transferred from one end to the other.
   Hence, When heat is supplied to matter, the energy of its molecules increases and they start vibrating vigorously.
