CONDUCTION |
-Transfer of thermal energy within an object. - No net movement of particles - Occurs in solids |
|
|
CONVECTION |
Transfer of thermal energy through the movement of particles. - Has a net movement -Occurs in liquids and gases |
|
|
Radiation |
-Transfer of energy waves. -Transfer of thermal energy with no movement of matter. - Electromagnetic radiation |
|
|
All objects...... |
emit and absorb thermal energy by radiation |
|
|
Specific Heat |
Energy required to raise 1kg of material by 1-degree celsius. |
|
|
Latent Heat |
Taking 1 kg of material and changing it to another state. |
|
|
An object that absorbs more energy... |
Decreases in temperature |
|
|
An object that absorbs more thermal energy... |
Increases in temperature |
|
|
Good Conductors=.... |
Gains/Loses thermal energy quickly |
|
|
Materials that are bad conductors of heat are... |
thermal insulators |
|
|
Insulators= |
Gain/loses thermal energy slowly |
|
|
Weins law: |
-Cool objects ( at lower energy) emit radiation at long wavelengths - Hotter objects emit radiation with a higher frequency |
|
|
Re-radiated electromagnetic radiation |
-Reflected -Transmitted -Absorbed |
|
|
Emissivity |
-An objects effectiveness of emitting energy |
|
|
The enhanced greenhouse effect
|
1) Total energy received 2) The amount that is lost back to space |
