Temperature The average amount of energy of motion of each particle in a substance. nyC4RgQ

Temperature and the Movement of Molecules The iced tea is cold, so its molecules move SLOWLY. The herbal tea is hot, so its molecules move FAST.

Temperature and the Movement 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 °CConvert 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. ***MAIN WAY TO MOVE HEAT THROUGH THE TROPOSPHERE!
