Heat transfer
Conduction, Convection, Radiation
Conduction
Heat can be transferred by conduction. When an object heated, the particles in the object begin to vibrate. These vibrations are passed on through the object, transferring the heat from one end to the other. An example of conduction is when you have a saucepan on a flame and it slowly conducts to the sides.
Convection
Heat can be transferred from one place to another via convection. In convection hotter particles rise and cooler particles fall circulating heat. An example for convection is when hot air rises when a heater is turned on and pushes the cold air down so that the heater can heat the particles in the cold air, and when the hot air becomes cold again it falls back down to the heater in a pattern until you turn off the heater.
Radiation
Radiation is the transfer of heat from one place to another using invisible waves. All objects out heat via radiation but hot objects radiate more heat than cool objects. Dark objects radiate more heat than light objects. An example of radiation is when a darker car radiates more heat then a lighter car.
