Thermal Energy - 6.9AB
Help!

|---|---|---|---|---|---|
| Thermal Energy | The total kinetic (motion) energy of tiny particles
that make up matter. The faster the particles
move, the warmer the matter becomes.
🗑
|
||||
| Conduction | Transfer of thermal energy that occurs in solids,
liquids, and gases when two substances of
different temperatures touch.
🗑
|
||||
| Convection | Heat transfer caused by the rising of hotter, less dense
fluids and the falling of cooler, more dense fluids.
🗑
|
||||
| Radiation | The transfer of energy by the movement of
electromagnetic waves or subatomic particles.
🗑
|
||||
| Heat | Energy transferred between two objects of different
temperatures; energy will continue to move in a
predictable pattern from warmer site to cooler site until
all sites have reached the same temperature.
🗑
|
||||
| Convection Current | A circular movement of fluids caused by the
rising of hotter, less dense fluid and the falling
of cooler, more dense fluid.
🗑
|
||||
| Law of Conservation of Energy | Energy can neither be created nor destroyed;
energy just changes form.
🗑
|
||||
| Temperature | Average kinetic energy of all the particles in a
material; measured by a thermometer in degrees
(usually Celsius or Fahrenheit).
🗑
|
||||
| Energy | The ability to do work
🗑
|
||||
| Substances | matter; a material of a particular kind or constitution
🗑
|
||||
| Thermal Energy Transfer | The movement of heat from one place to another.

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
