1. Thermal Energy (Heat energy)

2. EQ: What is the relationship between heat, thermal energy, & temperature?
Write the EQ at the VERY TOP of the RIGHT page
Title your page: TEMPERATURE & HEAT

3. Temperature & Heat
Temperature – measure of the AVERAGE value of KINETIC ENERGY of the molecules in random motion
2 units in SI (Metric System)
Celsius (0C)
Kelvin (K)
Thermal Expansion – ALMOST all substances EXPAND when heated and CONTRACT when cooled. The EXCEPTION is WATER!
Thermal Energy – sum of the KINETIC and POTENTIAL energy of all the particles in an object.

4. Temperature Conversion Equations…
Temperature & Heat
Temperature Conversion Equations…
Heat – thermal energy that flows from something at a HIGHER temperature to something at a LOWER temperature.

7. Transferring Thermal energy
Thermal energy is transferred from place to place by:
CONDUCTION
CONVECTION
RADIATION
Transfer of thermal energy by collisions between particles in matter (DIRECT CONTACT)
*occurs in SOLIDS, LIQUIDS, and GASES. METALS are BEST conductors of heat!*
Transfer of thermal energy in a FLUID by the movement of warmer and cooler fluid from place to place
*occurs in FLUIDS (liquids and gases). RISING of WARMER fluid and SINKING of COOLER fluid forms a CONVECTION CURRENT!*
Transfer of energy by electromagnetic waves
*Radiation is MOST important in GASES

8. Transfer of thermal energy
CONDUCTION
CONVECTION
RADIATION
Examples:
Touching a HOT pot
“shocking” someone by dragging your feet
Melting ice in your hand
Weather currents
Convection currents in the mantle of the earth
Water boiling in a pot
Heat you can FEEL
Heat from a fire
Heat from the sun
“wiggly” lines you see when you look across a HOT parking lot
DRAW this diagram of HEAT TRANSFER in your NOTEBOOK!

9. Transfer of thermal energy
Insulator – material in which heat flows slowly
Examples: wood, plastics (most), fiberglass, air, wool, clothing, oven mitts
Conductor – material in which heat flows quickly
Examples: most metals conduct heat/electricity
