This type of heat transfer is called conduction. Consider a metal rod that is heated up at one end with the help of candle.
Candle imparts thermal energy to the atoms in the metal rod. This energy makes atom vibrate and this in turn makes its neighboring atom vibrate hence producing a falling domino effect. So atoms do not move from their place but vibrate, and after while whole rod will be uniformly heated. A link can be found below.
Radiation is the mode of transfer of heat which does not require particles. Even through vacuum heat radiation can pass through. It is passed in the form of electromagnetic radiations. Heat radiations otherwise known as infrared radiations. It means that it is beyond the red end of the visible radiations named as VIBGYOR.
The heat transfer without direct contact is possible by convection and radiation.
No,the transfer of heat by the movement of heated fluid is called convection.
Energy transfer by convection is primarily restricted to fluids. One of the significant modes of heat transfer is convective heat transfer.
Convection is the movement of particles due to a gradient of energy. Heat energy is thus transfered by the moving particles.
That sounds like a description of heat conduction.
It is the process of transfer of heat from one place to other with actual movement of heated particles. Convention of heat take place in fluids and gases .
Radiant heat does not require particles. It involves light in the infrared range.
radiation. the particles are known as quanta.
Radiation is a type of heat transfer that does not require particles . how does the color of the penguin skin help it?
Heat Radiation does not need a medium (particles of matter).
Radiation.

Radiation is the only type of heat transfer that can occur through vacuum (space with no particles).
radiation air travels this way false or true?
Because conduction and convection require particles to transfer heat. Space is a vacuum (has no particles in it) so convection and conduction cannot occur.
That is called conduction.
Radiation does not need particles to transfer heat.
