Conduction is when heat is transferred through a material by passing thermal energy from molecule to molecule (from collisions). An example is when you heat up one end of a pan and the handle gets hot a little later.
Convection is when, as they say, heat rises. This applies to liquids and gases because their molecules are mobile. The hot molecules still stay hot, same with the cold ones, but they rearrange themselves so heat flows. One example is, as said before, hot air rises and cold air sinks.
Finally, radiation is a transfer of energy via electromagnetic radiation (light waves). This is how the sun heats stuff on the Earth.

What are three types of radiation used in cooking?
Conduction, Convection, Radiation
Does more energy reach us through conduction or radiation?
Most of the solar energy we get comes through radiation. So we get more energy via radiation, than conduction.
What are the three methods of energy transfer?
radiation convection conduction
Why can heat travel through space by radiation but not by conduction and convection?
For conduction and convection we need a material medium. But for radiation such a meaterial medium is not necessary. So in free space radiation can pass through easily.
How can an electric light bulb transfer heat in covection radiation and conduction?
Conduction: Heat travels via Metal parts on Bulb Convection Current: Hot air around bulb rises and cool air replaces it thus heat from bulb will consistantly warm up cool air around it. Radiation: Bulb is bright and shiny, thus emits infra red radiation. These are my opinion and they are not model answers. Mr Lin. from Singapore zillusia100 a.t. yahoo point com point sg
Conduction insulation radiation covection which of these is not a method of heat transfer?
Insulation is not a method of heat transfer.
Why does the energy from the sun travel to earth by radiation instead of by covection or conduction?
The sun moves through the electromagnetic waves. Conduction and Convection transfers energy between differences in density.
What form of energy is used to cook pancakes convection or conduction?
covection?
What are the three forms of heat transfer?
convection conduction and radiation
When the room becomes warm when the furnace is turned on which is the answer conduction convection radiation?
Conduction
What are the differences between the three methods of heat transfer?
Conduction, convection ,radiations are three methods of heat transfer. Conduction is carried out by direct contact with materials covection & radiation are carried out without any contact with the material
What are 3 types of heat transfer?
convection conduction radiation
What is the Movement of thermal energy is called?
Conduction.Convection.Radiation
How is radiation amd conduction alike?
Radiation and conduction are alike in the fact that they both transfer energy.
What are 3 types of energy heat transfers?
conduction, convection, radiation
What are the ways heat transfer?
theres 3 convection, radiation, and conduction
Is a vent a source convection conduction or radiation?
conduction
