- convection-convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy
- convection is a liquid or gas
- conduction is a solid
- Radiation the heat waves go through empty space
- empty space is called the vacuum
- 4 ways to transfer energy
- electric current
- Waves
- thermal/heating
- forces (mechanical)
- when a fuel is burned the two main waste products are carbon dioxide and sulphur dioxide
- carbon dioxide is the fossil fuel and helps cause global warming and climate change. This is produced when any fossil fuels are burned.
- Sulphur dioxide when dissolved in acid rain, this is mainly a problem for coal powerstations
