Heat and temperature
- ET- Hotter to colder body
- Temperature = Hotness, Arbitrary scale, C
  - Energy= Energy Transfer, Absolute Scale, J
- ET= Mass x SHC x Temp Change
  - Change in Temp
- ET= Mass x SLH
  - Change in state
Energy Transfer
- Home
  - Double Glazing, Insulation etc..
  - Shiny surfaces reflect infrared
    - Reduces enerygy transfer
- Sankey Diagrams
- Efficiency= Usefull output/ total imput x 100
- Conduction in solid transfers KE
  - Air insulator
- Convection caused by density change
  - Trapped air reduces
Waves Transfer Energy
- Wave Speed = Frequency x Wavelength
  - Energy of wave increases as length decreases
- Electromagnetic Spectrum
  - Radiowaves  Microwaves Infrared  Visible light  Ultraviolet  X-Rays  Gamma rays 
- Microwaves
  - Cooking
    - Infrared
  - Communication
- Digital and Analogue Signals
  - Digital Clearer
    - Many at same time
The Stable Earth
- Earthquake waves travel through Earth
- UV Causes Cancer
- CFC's ozone thinner
