Energy Transfer by Heating

Infrared Radiation
1. all objects emit infrared radiation
2. can travel through vacumes
3. part of the electromagnetic spectrum
4. it is just beyond visible red light
Surfaces and Radiation
1. dark matt surfaces are good absorbers of infrared radiation
2. they are also good emitters of infrared radiation
3. light shiny surfaces are good reflectors of infrared radiation
States of Matter
1. there are 3 different states
2. Solid, liquid, gas
3. Solid particles are close together vibrating on the spot
4. Gas particles are spread out and have a high mount of energy
5. Liquids are free to move to fill spaces and have more energy than solids as they move over each other
Conduction
1. mainly occurs in solids
2. most liquids and all gases are poor conductors
3. due to conduction heat and travel from one end of a solid to another
Convection
Evaporation and Condenstaion
Energy Transfer by design
Specific heat capacity
Heating and insulating buildings
