The Kinetic Theory of Matter & Thermal Energy

The Kinetic Theory of Matter

A theory that matter is composed of small particles, all in random motion

Thermal Energy

• Is the energy resulting from the motion of particles

Thermal Energy Continued

• Is a form of kinetic energy and is transferred by heat

State of Matter

• The state of matter an object takes depends on its thermal energy

Motion of Particles

• The motion of molecules in an object dictates what state of matter the object is

Thermal Energy and Motion

• An increase or decrease in thermal energy affects the motion of particles in an object

Increase in Thermal Energy

• If an object gains thermal energy, the motion of its particles increases

Decrease in Thermal Energy

• If an object loses thermal energy to the environment, the motion of its particles decreases

Energy Matters!

• Thermal energy is an important element of the Kinetic Theory of Matter

Explanation

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

Conclusion

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

Remember

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