What method of heat transfer does not require a medium to travel why is it important?
radiant For one thing, it's how heat energy from the sun reaches us.
What is a mechanism that heat transfer does not need a medium to travel through?
Radiant heat (electromagnetic waves) does not require a medium. Sunlight, infrared light, microwaves are all radiant heat in the form of electromagnetic radiation.
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 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.
What is the method of heat transfer does not require a medium?
That refers to radiation.

In which form of heat transfer is a medium not required?
Heat transfer by means of radiation doesn't heat the medium. In fact, radiation doesn't even require a medium in order to work. Strictly speaking, convection doesn't heat the medium either. Convection transfers heat by moving the medium around. Of course, heat also spreads throughout the medium by conduction while the convection is going on.
In which mode of transfer of heat does the medium not get heated up?
Infrared radiations. They do not require any medium. So they don't heat any medium. They don't even heat the air through which they pass.
Which method of heat transfer use a medium?
Both conduction and convection require an intervening medium, but convection requires the medium to be able to move.
What role does the sun have on how heat is transferred?
Due to nuclear reaction in the sun it emits enormous heat ,and heat does not require any medium to transfer.
What is heat transferred in?
Radiation in heat transfer is one of three known modes of heat transfer: conduction (as heat transfer in solids and less effective in liquids)), Convection (as in liquids and gases), and radiation (that not necessarily require a medium for the transfer). Heat of sun is transferred to us in the vacuum space by radiation heat transfer.
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.
