8P2D Heat Transfer and Molecular Motion

2. Thermal energy
The total amount of kinetic energy from the moving particles inside a piece of matter.
The faster the particles move, the warmer the matter can get.

3. Molecular Motion All molecules are in constant motion.
Molecules of a liquid have more freedom of movement than those in a solid.
Molecules in a gas have the greatest degree of motion.
Heat, temperature, and the motion of molecules are all related.

4. Heat always transfers from hot to cold.
Heat transfer
Thermal energy being moved from one object to another via conduction, convection, or radiation.
Important Tip!
Heat always transfers from hot to cold.

5. Conduction
Transfer of thermal energy that occurs in solids, liquids, and gases when two substances of different temperatures touch.

6. Conduction

7. Radiation The transfer of energy through matter or space
as electromagnetic waves, such as visible light
and infrared waves.

8. Convection
Transfer of thermal energy through circular motion caused by heating and cooling in fluids (liquids and gases).

9. Convection

10. Atom Collision
The result of two or more atoms striking each other and the release or absorption of energy.
