Heating by conduction takes place when two objects are touching, and heat flows from the hotter object to the cooler object. Heating by convection takes place when a hotter substance (such as air) expands and becomes less dense than the surrounding cooler substance, and therefore rises; the rising hot substance can then come into contact with something and heat it. Heating by radiation takes place by means of various types of electromagnetic radiation which transfer energy and can heat things up; sunlight is an example, which warms things up, or a microwave oven which is designed to rapidly heat water or anything that contains water.

What are three forms of energy transfer?
Conduction, convection and radiation. Conduction is when heat is transferred directly between materials. convection occurs when heated materials move from one place to another heating matter along the way. Radiation is when waves of heat move through space.
Why does the energy from the sun travel to Earth by radiation instead of by convection or conduction?
Convection and conduction require matter to travel through, and there is no matter between Earth and the Sun
What is required for conduction and convection but not radiation?
It is required in both that the pieces of matter are touching so that the heat travels through the matter and not empty space (Radiation)
How does heat travel through each state of matter?
If your talking a out the 3 basic states of matter it would be gas but if your going by the 4 basic states of matter it would be plasma.
What can radiation not do that convection and conduction can do?
Since radiation is done by electromagnetic waves, it can travel through space. i.e no matter is required. That way you can heat up objects through space. Or, for example, the earth gets heated by the suns electromagnetic waves.
What does conduction and convection uses that radiation does not?
Matter.

Does radiation require movement of matter?
no it doesn't, only conduction and convection

What important ability or property does electromagnetic radiation have that other energy transport processes such as conduction and convection do not?
Electromagnetic radiation can travel through a vacuum (like the vacuum of space), while conduction and convection require matter to do their thing.
What is Convection and conduction and radiation?
Conduction:- Conduction is the transfer heat from a hotter to a colder body by vibrating. Convection:- Is the main heat transfer mechanism in fluids. Radiation:- Radiation is the process of particles transferring heat through matter or space.
Do conduction convection and radiation all use matter?
Yes. Conduction must be a transfer of heat energy throughout a substance. Convection must be the circular movement of matter to move heat throughout. Radiation does not contain mass, but the radiation (i.e. photons) is still matter. Also, to create radiation, it requires matter.

How can heat move without having matter to move it?
By radiation. Only conduction and convection need a medium in which to move
