Question

Explain the following effects of heat.

Change in temperature

Short Note

Solution

Change in temperature :
When heat energy is added to a substance, the kinetic energy of its particles increases and so the particles move at a higher speed. This causes a rise in temperature. When a substance is cooled, that is, when heat is removed, the molecules lose heat, and its temperature falls.
