Thermal Transfer

1. Conduction

1.1. occurs in?

1.1.1. solid

1.1.2. liquid

1.1.3. gas

1.2. Metal

1.2.1. good conductor

1.2.2. transfer by : vibration of particles, moving of free electrons

1.3. non- metal

1.3.1. poor conductor/ good insulator

1.3.2. transfer by : vibration of particles

2. Convection

2.1. occurs in?

2.1.1. Liquid

2.1.2. gas

2.2. How

2.2.1. Works on density

2.2.2. when particles get heated, it expands and rises, then on the other hand the cooler particles with a higher density will sink. this creates a convection current.

3. Radiation

3.1. occurs in?

3.1.1. solid

3.1.2. liquid

3.1.3. gas

3.1.4. even in vaccuum

3.2. dull and black

3.2.1. good emitter of heat

3.2.2. good absorber of heat

3.3. Shiny and white

3.3.1. poor emitter of heat

3.3.2. good emitter of heat

3.4. generally

3.4.1. good emitter of heat are good absorber of heat.

3.4.2. Poor emitter of heat are poor absorber of heat
