Which kind of energy transfer can occur in a vacuum?
Radiation.
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.
The type of heat transfer that does not always require matter to occur?
Radiation by EM waves which can travel in a vacuum
What is the only way heat travels through a vacuum?
by radiation - convection and conduction cannot occur in a vacuum!
What are the different types of heat transfer?
There are three types of heat transfer, namely conduction, convection and radiation. Heat is transferred until the reach a state of equilibrium. Conduction is basically the transfer of heat through a surface of contact, such as a fire to the base of a pot. We say that a material is a good or poor conductor of heat when heat travels quickly or slowly in that particular material. Good conductors of heat are metals whereas poor conductors of heat are rubber and Styrofoam. Conduction cannot occur in a vacuum. Convection is the transfer of heat through molecules. It can only occur in liquids and gases as there are relatively big spaces between the molecules. A convection current is where hot air rises and cold air sinks. Convection cannot occur in a vacuum. Radiation is the transfer of heat through a vacuum. Heat is transferred from the Sun to Earth through radiation.
How does energy transfer from sun to the atmosphere?
radiation can occur through a vacuum
Radiation is the only type of heat transfer that can occur?
Radiation is the only type of heat transfer that can occur through vacuum (space with no particles).

What type of heat transfer is it when we receive sunlight?
It is radiation, as that is the only heat transfer that can occur in a vacuum (the universe).

How is the suns energy transferred?
The sun transfer heat through radiationAnswer'Heat' is not transferred. Rather, 'heat' describes the process of transferring energy. So, your question should read, 'How does the sun transfer energy to earth?", and the answer is by radiation.

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.
How does the temperature remain constant in a vacuum flask. Explain why in can do so over a long period of time?
Vacuum is a great insulator, because there needs to be some medium for processes of conduction or convection to occur. The only possible way to transfer heat through vacuum is radiation, which is not as effective, especially that flask walls are also constructed to limit radiation heat transfer(they are reflective). Temperature stays the same if there are no means to transfer energy between interior end environment.
Which mechanism of heat transfer can work in a vacuum?
Heat is a form of energy. Atoms of a certain material begin to tremble very fast when heated and pass this movement on to other atoms. So I think -not shure, heat/ energy can only be passed through material, and so it is not possible in a vacuum.
