Introduction
• Thermal energy is the energy of a body arising from motion of its atoms or molecules. • It is directly proportional to the temperature of the substances. • Temperature is directly proportional to the average kinetic energy of the particles in a substance.
Pre-Requisites:
molecule, kinetic energy, particle
Activity:
Heating a pot of water.
Real Life Question:
What makes a substance hot?
