6.9 Vocabulary Review

The total kinetic (motion) energy of tiny particles that make up matter. The faster the particles move, the warmer the matter becomes.

• Radial Energy

• Thermal energy

• Polar Cells

• Solar Energy

Conduction is the transfer of thermal energy that occurs in solids, liquids, and gases when two substances of different temperatures touch.

• True

• False

Heat transfer caused by the rising of hotter, less dense fluids and the falling of cooler, more dense fluids.

• Conduction

• Convection

• Radiation

• Thermal Energy

The transfer of energy by the movement of electromagnetic waves or subatomic particles.

• Convection

• Radiation

• Conduction

• Heat Waves

Energy Transferred between two objects of different temperatures; energy will transfer until all objects are the same temperature.

• Heat

• Radiation

• Conduction

• Convection

A circular movement of fluids caused by the rising of hotter, less dense fluid and the falling of cooler, more dense fluid.

• Wind Current

• Ocean Current

• Convection Current

• Density Current

The law of conservation of Energy states that energy can neither be created nor destroyed; only transformed.

• True

• False

The average kinetic energy of all the particles in a material; measured by a thermometer in degrees ( usually in Celsius or Fahrenheit)

• Heat

• Cold

• Temperature

• Conduction

A spoon becoming the same temperature as the hot soup that it is sitting in is an example of Radiation.

• True

• False

The thermal energy process continues to take place after both substances attain the same temperature.

• True

• False
