For heat transfer by radiation, no medium is required. It can occur through a vacuum because it involves the transfer of electromagnetic waves, such as infrared radiation, from a hotter object to a cooler one. The rate of radiation heat transfer depends on the temperature difference between the objects and their surface properties.
What else can I help you with?
In which process of transfer of heat in which material medium is not required?
Radiation is the process of heat transfer where material medium is not required. Energy is transferred through electromagnetic waves such as infrared radiation or light. This process can occur in a vacuum as well.
What is required for conduction and convection but not radiation?
Material medium is required for conduction and convection to transfer heat, but it is not necessary for radiation. Conduction involves the transfer of heat through direct contact between materials, while convection involves heat transfer through the movement of fluids. Radiation, on the other hand, can occur in a vacuum because it involves electromagnetic waves.
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.
What is required for heat to be transferred by radiation?
Heat transfer by radiation requires a source of electromagnetic radiation, such as infrared light, to emit energy. The objects involved must have a temperature difference in order for heat to flow from the hotter object to the cooler one. Additionally, there must be no medium (such as air or water) between the objects to obstruct the transfer of heat radiation.
The sun heating a lake is what type of heat transfer?
The sun heating a lake is an example of heat transfer through radiation.

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.

What are 3 types of heat transfer?
The three types of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through direct contact, convection is the transfer of heat through the movement of fluids or gases, and radiation is the transfer of heat through electromagnetic waves.
What are the three forms of heat transfer?
The three forms of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through direct contact of particles, convection is the transfer of heat through the movement of fluids or gases, and radiation is the transfer of heat through electromagnetic waves.
Is radiation the transfer of heat by the movement of a fluid?
No, most forms of radiation have nothing to do with heat. Transfer of heat by the movement of a fluid is called convection.
What is The heat transfer?
Radiation
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.
What can radiation not do that convection and conduction can do?
Since radiation is done by electromagnetic waves, it can travel through space. i.e no matter is required. That way you can heat up objects through space. Or, for example, the earth gets heated by the suns electromagnetic waves.
