Which method of energy transfer does not involve the movement of matter?
Energy transfer takes place by convection (the movement of hot air or other fluids due to diferences in densiity), conduction (transfer of heat through contact - caused by collisions between adjacent particles), or radiation (the transfer of energy by electromagnetic waves such as light or infra-red rays).Radiation requires matter to create and absorb the EM waves, (i.e. you need a hot object to give off the IR waves) but the waves themselves can travel through a vacuum, so do not require matter to transfer energy.
What wave doesn't need matter for energy transfer?
Electromagnetic waves; gravity waves.Electromagnetic waves; gravity waves.Electromagnetic waves; gravity waves.Electromagnetic waves; gravity waves.
One property that makes electra magnetic waves differ from other types of waves is?
they do not need a medium to transfer energy.
What do not need matter to transfer energy?
Energy can travel through empty space as electromagnetic waves (light, etc.), or as gravitational waves. Changes in the electric and magnetic field are also energy transfers without matter. However, please note that any energy has, by itself, an associated mass.
Heat from the sun reaches you by which form of heat transfer?
Radiation This is because between the Sun and the earth there is a vacuum (there are no air molecules). So conduction and convection will be no use as they need molecules and atoms to work: they transfer heat through them or the molecules carry the heat. HOWEVER: Radiation needs no particles or atoms or molecules or anything for heat transfer, so the sun's light energy is transferred to us by radiation.
How mechanical and electromagnetic waves are similar.?
Electromagnetic waves can travel through space.Mechanical waves need matter to transfer energy.

What waves transfer from one place to another?
All waves can travel from one place to another as long as they have a medium to travel through. The only waves that do not need a medium are electromagnetic waves. When using the word "transfer" though. Waves transfer energy; waves themselves are not transfered they simply travel.
Why does sound need a medium to transfer vibrations?
Sound means that some molecules transfer their vibrations to other molecules. So, because of this, obviously you need molecules to transfer sound.Sound means that some molecules transfer their vibrations to other molecules.

Does it take less energy to heat hotter water than colder water?
Yes, as the molecules of the hot water are already in motion, they need less energy to speed up and transfer it whereas the molecules of cold water need far more energy so that they get into motion and then transfer energy.

they do not need a medium to transfer energy.
What type of wave can transfer energy without medium?
the wave which does not travel through a medium is called electromagnetic wave.
Do mechanical waves need a medium to transfer energy?
Yes. For example, sound needs media (air, water, etc.) to propagate.

State and discuss the modes transfer of heat?
The modes of transfer of heat are: # Conduction # Convection # Radiation In Conduction, heat is transferred along the material by the vibration of molecules. The molecules, however, don't actually move from their positions. It is usually seen in solids only. Heat transfer in Convection is by actual movement of material molecules. It is seen in liquids and gases. Radiation is the mode of transfer which does not need any material medium. The transfer of heat is done by electromagnetic waves.
