Revision
Conduction and Convection
1. Energy transferred from the radiator to nearby air particles = conduction
2. Air by radiator = warmer = less dense
3. Warm air rises = replaced by cooler air = cooler air heated by radiator
4. At same time = previously heated air transfers energy to surroundings = cools = more dense = sinks
5. Cycle repeats = flow of air circulates the room = convection currents.
