heat transfer happens because objects that have energy, meaning vibrating atoms will bump against others and transfer the energy to the other atoms and so on. and also because things always have a tendency to have more entropy as time passes.

Which type of heat transfer can happen even if there are no particles of matter?
Heat Radiation does not need a medium (particles of matter).
What will happen when a cold material interacts with a hot material?
The heat will transfer from the hot material to the cold material. Heat tends to go where it is not.
The transfer of heat by fluid?
The transfer of heat by fluid is convection.
Is convection the main type of heat transfer?
No, in the universe radiation heat transfer is by far the largest transfer.
Is conduction a heat transfer by direct contact of particles of matter?
Yes, whereas convection heat transfer is the transfer of heat via a liquid, and radiative heat transfer occurs through empty space (like the heat you feel from the sun).
Where can heat transfer happen?
any where but condition is there should be temperature difference
Which type of heat transfer can happen even if there are no particles of matter?
Heat Radiation does not need a medium (particles of matter).
What is convective heat transfer?
Convection heat transfer is the transfer of heat by the movement of a fluid.
What will happen when a cold material interacts with a hot material?
The heat will transfer from the hot material to the cold material. Heat tends to go where it is not.
What are two examples of heat transfer?
Convection - heat transfer through liquids.Conduction - heat transfer through solids.Radiation - heat transfer through vacuum.
How does temperature affect the rate of heat transfer?
For conductive and convective heat transfer, the rate of heat transfer is proportional to the the temperature difference; if you double the difference you will double the rate of heat transfer. For radiative heat transfer, the rate of heat transfer is proportional to the difference of the 4th powers of the absolute temperatures.
What is convective heat?
Convection heat transfer is the transfer of heat by the movement of a fluid.
The transfer of heat by fluid?
The transfer of heat by fluid is convection.
What are the examples of heat energy?
Heat energy involves the transfer of energy from a hotter body to a colder one. This can happen via radiation, conduction, or convective circulation.
What do conduction and convection have in common?
They're both modes of heat transfer via material media.
Winds transfer heat energy by what method of heat transfer?
convection
How heat transfer is controlled?
There is a special mechanism that controls heat transfer.
