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.
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.
How do you explain the difference between conduction convection or radiation can transfer heat explain?
It's a different way to transfer heat. One object emits electromagnetic radiation (for example, infrared - though it depends on the temperature); another object absorbs it. Heat transfer through radiation can occur in empty space; with conduction and convection, that's not possible.
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.
What does heat travel through space as?
By Radiation. There Are three modes of heat transfer depending on medium(like fliud or solid). Conduction(solids and fliuds), Convection (fliuds) and Radiation(vaccum). In space there is no medium i.e,Vaccum.So that in space the heat transfer the mode of radiation.

What three ways can heat travel through substances?
Conduction - Process of heat transfer through a medium or material without any movement of the medium or material. Convection - transfer of heat from one place to another through the movement of fluids. A fluid with a given density rises within a fluid of greater density and sinks within in a fluid of smaller density. Radiation - transfer of heat, in the form of waves from one place to another without a medium.

What are two examples of heat transfer?
Convection - heat transfer through liquids.Conduction - heat transfer through solids.Radiation - heat transfer through vacuum.

What is the fastest heat transfer?
It depends on the medium of heat transfer. For solids, it is conduction heat transfer. For liquids and gases, it is convection heat transfer. for vacuum (no medium), it is radiation heat transfer.
Where to apply Darcy number?
The Darcy number is normally used in models of the transfer of heat through a porous medium.
How is heat transfer by radiation different form heat transfer by convection and conduction?
Radiation requires neither contact (through which conduction transfers heat) nor mass flow or movement (through which convection transfers heat). Only radiation can take place in a vacuum. Convection and conduction both require a material medium for the heat transfer to occur. Only radiation can transfer thermal energy through the vacuum of space.
What is the relationships of radation conduction and convection?
radiation is heat transfer through light (both visible and not). with a nuclear bomb, surrounding distant flammeables combust because of irradiated infrared energy. conduction is heat transfer through direct contact. a pot on the stove gets heated by the flame that touches it. convection is heat transfer through a medium (really really slow).
How is heat transferred through a radiator?
Convection, which is the transfer of heat by thermal currents in the air (or other medium)
