Heat Transfer Chapter 4
Three Types of Heat Transfer Conduction Convection Radiation Heat always travels from areas that are warmer to areas that are cooler Warm to Cool or Hot to Cold
Conduction Conduction is the process that moves heat energy from one object to another when they are touching Occurs only in solids Metals are good conductors of heat
Convection Convection is the process that transfers heat energy in through liquids and gases Helps to explain weather changes and volcanoes/plate tectonics
Radiation Radiation is heat energy that travels as electromagnetic waves through air. Sun is the biggest source of radiation energy
Conduction, Convection, & Radiation
Heat Transfer in a Nutshell Conduction- heat transfer through solids Convection- heat transfer through liquids and gases Radiation - heat transfer through gases Insulators- used to slow the transfer of heat energy from warmer objects to cooler objects. Good insulators are wood, fiberglass, plastic, paper, foam
