1. Temperature Changes 2. Transferring Energy 3. Electricity 4. Efficiency in Percentage 5. Controlling Energy Transfer 6. Paying for Energy
|
Internal (Thermal) Energy -> Energy stored in the movement of particles
|
Amount of internal energy depends on temperature, materials, mass
|
|
Temperature -> How hot or cold something is
|
|
|
Formula: Efficient Powers / Total Amount of Electricity Produced x 100% = Percentage
|
4/40 x 100% = 100
|
|
Formula: Q = mcAT
|
Q -> Amount of heat transfered
|
|
M = Mass
|
C = Specific Heat Capacity
|
|
A = The changes in temperature
|
T = Temperature
|
|
Unit (Times, Energy, Power wrattings)
|
Electricity and gas are paid base on usage and measure in KwH
|
|
Formula -> KW x H x KwH (Hour)
|
|
|
Appliances -> Machines
|
Power -> Different appliance transfer different amount per second
|
|
Wratts -> Method measurement of the rate of electricity
|
Power rattings -> Max amount of power a device produce under normal circumtances
|
|
Efficiency -> Ratio of useful energy from total energy
|
Sankey Diagram -> Diagram that shows efficiency
|
|
Evaporation
|
Conduction -> Passing vibrations (heat)
|
|
Radiation -> All objects emit infrared radiation (hotter, emit more, no need medium, thermal imagers)
|
Convection -> Cooler fluid sink, hotter fluids rise
|
|
Insulation -> Retain warmth inside the house and reduces fuel costs.
|
Air is only good conductor if it is trapped
|
|
To test insulation effectiveness, use containers with different insulating materials and measure temperature changes over time.
|
Light color -> Reflect energy, while Dark color -> Emit radiation
