THERMAL ENERGY
THE ENERGY OF MOVING ATOMS...??? THE ENERGY OF HEAT......?????
IT'S THE TOTAL KINETIC ENERGY OF ALL THE ATOMS IN A SUBSTANCE.
ALL OF THIS LESSON EXPLAINED IN 5 MINUTES....
WHAT'S THE DIFFERENCE BETWEEN THERMAL ENERGY AND TEMPERATURE?
FOR YOUR NOTEBOOK:
Lesson 9: Thermal Energy
Vocabulary and Notes:
Thermal Energy - The total amount of kinetic energy of all atoms or particles in a substance.
Temperature - The average kinetic energy of each particle or atom in a substance.
Heat - When thermal energy flows from an area of more thermal energy, to an area of less thermal energy.
A. Key Concepts of Thermal Energy
1. It's the total kinetic energy of the particles!
2. Atoms don't look like they move because they are so small!
3. Thermal is the reason substances change their state of matter. (Examples: Melting, Condensation)
B. Key Concepts for Temperature
1. If I take every atom in a substance, and then measure it's kinetic energy, I'd average all the measurements to find temperature.
2. The reason the red goes up on a thermometer is because the liquid molecules are rising in kinetic energy. They collectively are moving so fast that they can only bounce themselves upward. Hence, a rise in temperature.
C. Key Concepts for Heat
1. It's the flow of thermal energy!
2. It transfers from one substance to another in a variety of ways. (touch, waves, and directional flow)
3. Thermal energy always evacuates from a crowd of itself, to an area of less of itself. Hot --> Cold
