Temperature
The average amount of energy of motion of each particle in a substance.

Temperature and theMovement of Molecules
The iced tea is cold, so its molecules move SLOWLY.
The herbal tea is hot, so its molecules move FAST.
Temperature and theMovement of Molecules
HOT - molecules move FAST.
COLD - molecules move SLOWLY.
Thermal Energy (Heat Energy) – The total energy of MOTION in the particles of a substance.
A pot of tea would have more thermal energy than a cup of tea because
there are more molecules!
Temperature
Heat causes the molecules in the thermometer liquid to move quickly and expand!
Temperature
Lack of heat causes the molecules in the thermometer liquid to move slowly, contract and sink!
Temperature
Measured in Celsius, Fahrenheit, and Kelvin
0˚C
32 ˚F
100˚C
212 ˚F
Temperature
Temperature Conversions: °C = 5/9 (°F – 32) °F = 9/5 °C + 32
Convert 72 °F to °C Convert 2 °C to °F
Which graph correctly shows the effect of heat energy on the motion of molecules of matter?
The transfer of thermal energy from one object to another because of a difference in
temperature.
Heat
Radiation
The direct transfer of
energy from electromagnetic
waves.
Examples: Heat from the sun, holding hands in front of a fire/heater, burner on
stove giving off heat.
Conduction
The direct transfer of
energy from one substance to
another that is touching.
Examples: A pot sitting on the stove, a heating pad resting on your back, feeling
for a fever, touching the hotplate.
Convection
The transfer of energy by the
movement of a fluid.
Examples: Boiling water, lava lamp (warm fluid rising and cool fluid sinking).
Convection Currents
The circulation of a fluid as it
alternately heats up and cools
down.

1.List as many facts as you can since we began this unit on Monday.
2.After 5 minutes, get up and find a partner.
3.Find one idea your partner has on their list that you don’t have and jot it down.
4.Once you give an idea and get an idea, move on to another partner.
