If you mean electrical conduction, that requires electrical charges that are fairly free to move around.

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.
Write the condition required for conduction of heat?
It require the medium with conduction property. The medium must be stable enough to withstand heat and not thermally decompose. It is then apply temperature difference to start such conduction heat transfer.
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
Does conduction require direct contact?
convection requires a medium to travel. In space there is no air but, a vacuum. Therefore direct heat from the sun is radiation as it does not require a medium to travel.
Why can't heat energy travel through space by conduction or convection?
Both of these methods require the presense of matter.Both of these methods require the presense of matter.Both of these methods require the presense of matter.Both of these methods require the presense of matter.
Does conduction require a medum?
Yes, since there would be no conduction of sound in a vacuum.
Does conduction require medium?
Only for trains and orchestras.
Does radiation require movement of matter?
no it doesn't, only conduction and convection

Why is radiation different to conduction and convection?
because, RADIATION occurs only in vaccum.. It does not require a medium to travel... where as conduction and convection require medium to travel. CONDUCTION: heat transfer between homogenous molecules(i.e.) flow of heat inside a body from one point to another. CONVECTION: heat transfer between two mediums(i.e) flow of heat from a metal to air surrounding the metal.
Why a UJT is not a thyristor?
Because to remain in conduction it requires a supply of emitter current. Without a minimum value of emitter current it can't stay in the on position. Most thyristors do not require gate current after they are turned on to remain in conduction
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.
