Transfer of heat

1. Radiation

1.1. does not require a medium

1.2. good emitters are good absorbers

1.3. black surfaces better emitters and absorbers than white

1.4. factors that affect

1.4.1. colour and texture

1.4.2. surface temp

1.4.3. surface area

2. Convection

2.1. only in liquids and gas

2.2. not in solids, solids cant flow

2.3. warmer part expands and rises

2.4. cooler part sinks to replace

3. Conduction

3.1. happens in solids

3.2. metals have free electrons that help transfer energy

3.3. metals and non metals transfer through particles

3.4. metals transfer energy faster due to electrons
