Thermal Engergy
- Thermal Energy Transfer
- Conduction
- Through Substanses
- No Movement
- Metals Are Good Conductors
- Wood Is A Good Insulator
- Convection
- Through Fluids
Anmerkungen:
- Fluids = Liquids And Gases
- Upward Movement Of Warmer Fluids
Anmerkungen:
- Warmer Fluids Are Less Dense
- Radiation
- Thermal Radiation
- Through IR Waves
Anmerkungen:
- IR Waves = Infa Red Waves
- Travels In Straight Lines
- Shiney Surfaces Reflect It
- Emmit Less Heat Through Thermal Radiation
- Matt Black And Darker Surfaces Are Good Absorbers
- Energy Efficient Homes
- Where Heat Is Lost
- The Walls

- Reduction Of Heat Loss
- The Walls
- Good Insulation Building Materials. Must Be:
- Strong
- Durable
- Easily Available
- Cavity Gap
- To Stop Convection
- Can Be Filled With Fiber Glass
- Outer Wall Of Brick, Inner Wall Of Thermal Bricks
- The Windows
- Glass
- Poor Conductor Of Heat
- Double Glazing
- 2 Thin Layers Of Glass To Improve Insulation
- Triple Glazing In Very Cold Countries
- The Roof
- Similar To Insulation Of Walls
- Cavity Gap
- Loft Insulation
