- Insulating Homes and Specific Heat Capacity
- Saving energy by insulating the home
- Covering the loft floor and hot water tank with fibreglass wool reduces conduction and radiation
- Injecting foam into cavity walls reduces convection and radiation
- Fitting draught-proofing around doors reduces convection
- Fitting double glazing reduces conduction and radiation
- U-Values
- Shows how quickly heat travels through a material
- Lower the U-Values, the better the material is as an insulator
- Specific Heat Capacity
- The amount of energy that is required to change the temperature of 1kg of the substance by 1C
- Calculates how much energy is stored in an object
- Calculates how much energy is required to raise the temperature of a material by a certain amount
- Concrete and bricks have a high SHC - they store heat energy at night and gradually release it during the day
- Saving energy by insulating the home
