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.

Which can travel through empty space out of insulator convection electomagnetic conduction or radiation?
Radiation can travel through empty space. The radiation in question is electromagnetic waves.
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.
How does heat travel in solids and liquids?
a. condensation b. conduction c. convection d. radiation
Does convection or conduction travel at the speed of light?
No. The speeds of convection and conduction vary, but they are nowhere near the speed of light.
What mediums can heat travel through?
Heat can move in three ways: conduction, convection, and radiation. In conduction, physical contact between two surfaces is required. The molecules of the heat source bang into the molecules of the heat sink, imparting some of their energy in the process, thus reducing the temperature of the heat source while increasing that of the heat sink. Heat can move by conduction through pretty much any mass, whether solid, liquid, gas, supercritical fluid, or plasma. In convection, a substance is heated by the heat source and then moved to another location where it can release some of its energy as heat. In the case of natural convection, the motion is a result of buoyancy forces, while in forced convection something like a fan or pump is responsible for moving the heated mass. For heat to travel in this manner the medium must be capable of movement - which generally excludes solids but includes gases, liquids, supercritical fluids, and plasmas. In radiation no medium is required to get the energy between the source and the sink. Heat can travel via radiation through a vacuum.
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

Radiation can travel through empty space. The radiation in question is electromagnetic waves.
Why can heat travel through space by radiation but not by conduction or convection?
Because conduction and convection require particles to transfer heat. Space is a vacuum (has no particles in it) so convection and conduction cannot occur.
Heat can be moved through liquid and gas by what?
Heat can travel by conduction, convection and radiation in liquids and gases.
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.
How is heat transfer by radiation different from both convection and conduction?
The main difference is that radiation can travel through any medium. Therefore, it is different.
Does heat travel as longitudinal wave?
No. Heat can traveled by conduction, convection, or radiation. Conduction and convection do not involve waves. When heat travels be electromagnetic radiation it takes the form of transverse waves.
How does energy travel to Earth?
There are three types of transferrable energy: conduction, convection, and radiation. Conduction- heat that moves from solid object to solid object by physical means. Convection- heat that moves about a gaseous object (think about boiling water) Radiation- light energy that can travel through space and needs no object to transfer through. The correct answer for this question would be radiation.
Why heat can travel through space only by radiation?
there is no medium for conduction or convection. all energy must be received from radiative sources.
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.
Is the suns energy radiant?
Yes. Here's a logical proof: There are three ways to transfer energy from place to place: --Conduction, --Convection, --Radiation. Conduction and convection need a 'medium' ... a substance to conduct or convect through. Radiation doesn't need anything to travel through. There is no medium ... no substance ... in the space between the sun and the earth, but heat and light from the sun reach the earth constantly. Since there is no medium for it to travel through, it can't be getting here by means of conduction or convection. The only possibility is radiation.
