  3. G&L Flashcards collection and grading - Thursday, Dec. 2nd

Today’s Lesson:

  1. Temperature - the average KE of the particles that make up a material

    • atoms or molecules

    2. adding (or losing) thermal energy increases (or reduces) KE of particles

    • as average KE increases - so does temperature.

    • as average KE lowers - so does temperature

    3. Two material may be the same temperature but contain different amounts of thermal energy.

    • ex. A pond and a puddle at the same temp

      • pond would have more thermal energy because its larger

    • in general solids and liquids have more TE than gases at same temp

      • particles are closer together so have more PE

4. Temperature is measured in degrees using a thermometer.

  • Degree Fahrenheit and Celsius are most common

  • Degrees Kelvin only used in science

5. Conversions

6. Heat - movement of thermal energy (TE) from a warmer object to a cooler

  • “heating” an object means adding TE to it.

  • “Cooling” means removing TE from it.
