|---|---|---|---|---|---|
| conduction | the transfer of heat energy by molecular and electron collisions within a substance (especially a solid).
🗑
|
||||
| insulators | substances that are poor conductors because the outer electrons are firmly attached.
🗑
|
||||
| convection | the transfer of heat energy in a gas or liquid by means of currents in the heated fluid. The fluid moves, carrying energy with it.
🗑
|
||||
| radiation | the transfer of energy by means of electromagnetic waves.
🗑
|
||||
| radiant energy | energy that is transferred via radiation.
🗑
|
||||
| electromagnetic waves | the form through which radiant energy is transferred.
🗑
|
||||
| electromagnetic spectrum | the range of frequencies at which radiant energy can travel.
🗑
|
||||
| terrestrial radiation | the radiation that is emitted by Earth to outer space
🗑
|
||||
| Newton's law of cooling | the rate of loss of heat from a warm object is proportional to the temperature difference between the object and its surroundings (Similarly for the gain of heat by a cool object.)
🗑
|
||||
| greenhouse effect | Warming of the lower atmosphere by short-wavelength radiation from the Sun that penetrates the atmosphere is absorbed by Earth and is reradiated at longer wavelengths that cannot easily escape Earth's atmosphere.
🗑
|
||||
| global warming | the result of an increase of greenhouse gases causing an increase of reflection of radiant energy by the atmosphere.
🗑
|
||||
| solar power | Energy per unit time derived from the Sun
🗑
|
||||
| solar constant | 1400 J/m2 received from the Sun each second at the top of Earth's atmosphere on an area perpendicular to the Sun's rays; expressed in terms of power, 1.4kW/m2

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.
