Using Infrared Radiation
To see is something is warm or cold blooded / to see is you have good insulation in your house / to see how warm something is.
1 of 18
Emit
Something that gives something off. E.g. Sun emits heat.
2 of 18
Absorb
Something that collects something. E.g. sponge absorbs water.
3 of 18
Thermal Radiation
Thermal Radiation is heat energy that is given off by all objects. Hotter, larger, objects give off more thermal radiation than smaller cooler ones.
4 of 18
Convection
Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it.
5 of 18
Radiation
In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium.
6 of 18
Conduction
Conduction is the process by which heat energy is transmitted through collisions between neighboring molecules.
7 of 18
Thermal Absorbtion
Black is the best thermal absorber of radiation.
8 of 18
Thermal Emission
Silver surfaces are bad emitters of thermal radiation.
9 of 18
Power
How much energy is transferred to an electrical devise in a given time.
10 of 18
Payback
The time it takes for you to ave saved enough money on your energy bill to counter the cost of the purchase.
11 of 18
Non-Renewable
Oil / Coal / Nuclear
12 of 18
Renewable
Wind / Solar / Tidal / Wave / Hydroelectric / Geothermal
13 of 18
Step-Down Transformer
A step-down transformer is used to decrease the voltage.
14 of 18
Substation
High voltage transmission lines transfer the electricity to a substation where the electricity goes through a step-down transformer.
15 of 18
Step-Up Transformer
A step-up transformer is used to increase the voltage
16 of 18
National Grid
When electricity has been generated it needs to be distributed to consumers. The electricity you use is transferred around the country by the National Grid.
17 of 18
Main Grid
This is the electricity that is available whenever you switch on an appliance at home
