How thermal energy is involved in and a big part of the Kinetic Theory of Matter.

1. The Kinetic Theory of Matter &
Thermal Energy

Block 4

2. The Kinetic Theory of Matter
A theory that matter is composed of small
particles, all in random motion

3. Thermal Energy
• Is the energy resulting from the motion of
particles

4. Thermal Energy Continued
• Is a form of kinetic energy and is transferred
by heat

5. State of Matter
• The state of matter an object takes depends
on its thermal energy

6. Motion of Particles
• The motion of molecules in an object dictates
what state of matter the object is

7. Thermal Energy and Motion
• An increase or decrease in thermal energy
affects the motion of particles in an object

8. Increase in Thermal Energy
• If an object gains thermal energy, the motion
of its particles increases

9. Decrease in Thermal Energy
• If an object loses thermal energy to the
environment, the motion of its particles
decreases

10. Energy Matters!
• Thermal energy is an important element of
the Kinetic Theory of Matter

11. Explanation
• A gain or loss of thermal energy affects the
motion of particles

12. Conclusion
• The Kinetic Theory of matter is all about
motion of particles therefore the two are
related

13. Remember
• “Loss or gain of thermal energy is what makes
the world go.” Mr. McCarthy
