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'.
No, it can only travel by radiation.
as electromagnetic radiation
Energy from the sun travels through the vacuum of space by radiation.
Radiation is the transfer of energy through a vacuum.
No, it won't. That's because the concussive blast wave (and sound, too, for that matter) requires a medium to travel through. That medium must conduct (carry or transfer) the energy of the wave. No mechanical medium equals no mechanical wave. However, if there are components of the blast that involve light or other kinds of electromagnetic radiation, those components will travel through the vacuum of space. They will not have the concussive impact that earth-bound waves will have.
We cannot hear the explosions from the sun as sound cannot travel through a vacuum, and the sound would have to travel through one to reach the Earth.
You are probably thinking of thermal convection and conduction.
Due to the vacuum of space there is no convection or conduction. Energy is transported by photons from the Sun to Venus (radiation).
Electromagnetic radiation can travel through a vacuum (like the vacuum of space), while conduction and convection require matter to do their thing.
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.
It can travel through a vacuum.
No. radiant energy (including heat) can pass though 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.
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.
No! Convection would require a medium and there is none such between the sun and the earth - just vacuum.
