Actually heat cannot travel through vacuum. sun emits radiations (obviously electromagnetic radiations.) which needs no medium to travel. hence these radiations travel through space and reaches earth where it interacts with atmosphere. when these radiations fall on media like air, water land etc. the radiation is converted into heat energy. Thus it is clear that heat from sun is converted into radiations which travel through space and reaches earth where it is converted to light.

No, Heat can travel through a vacuum. However it can not travel through a vacuum by convection because there are no particles in a vacuum. convection is the upward movement of particles as they warm up. An example would be hot air moving upwards.

Without medium, the only mode of heat transfer available is thermal radiation when the heat was emitted as photon and travel through vacuum to another surface.

In Quantum Physics, Light from the sun is considered as quantas [That means small energy packets]. Light & all the radiations from sun are moves through vacuum is in the form of 'Quanta'.

What is the kind of energy that can travel through different mediums but cannot travel through a vacuum?

You are probably thinking of thermal convection and conduction.


How does thermal energy travel through space from Sun to Venus?

Due to the vacuum of space there is no convection or conduction. Energy is transported by photons from the Sun to Venus (radiation).


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.


Can heat travel by convection through a vacuum?

No. Convection requires a carrier to convey the heat. Vacuum says there is nothing to do the conveying. Radiation does not need a convector, so heat can travel by radiation through a vacuum, like the radiation from the sun.

Can energy travel through a vacuum?

Yes.

electromagnetic energy


How light energy different from other energy?

It can travel through a vacuum.


Does radiation require a heated liquid to transfer energy?

No. radiant energy (including heat) can pass though a vacuum.


Is it possible for heat to flow across a vacuum?

Heat needs something to "flow" through. In a vacuum it will not have a medium to travel through and so heat cannot flow across a vacuum. Radiant heat will travel through a vacuum but here it is the light energy that is passing through the vacuum, not the heat energy.


Where can sounds not travel?

Sound cannot travel in a vacuum. Sound is mechanical energy, and it travels by the transfer of mechanical energy through the medium through which it is traveling. If there is nothing to transfer the mechanical energy, like there is nothing in a vacuum, sound cannot travel there.


Does Energy from the Sun is transferred to Earth through convection?

No! Convection would require a medium and there is none such between the sun and the earth - just vacuum.
