| P1a - Heating Houses | Energy flows from a warmer to a colder body |
| A thermogram uses colour to show temperature. | Hottest areas are white/yellow Coldest are black/blue/purple |
| Definitions of Temperature and Heat | Temperature - How hot something is Heat - Measure of thermal energy contained in a object |
| Specific Heat Capacity | Energy(J) = mass(kg) x specific heat capacity x temperature change |
| Specific Latent Heat | Energy(J) = mass(kg) x specific latent heat |
| There is no temperature change during changing state. | This is because the energy is needed to break the bonds that hold the molecules together. |
