Radiation is a type of heat transfer that doesn't require molecules because it can travel through empty space or a vacuum. Examples of radiation heat transfer include the heat from the sun reaching the Earth and infrared radiation emitted by a hot object.

What is the energy transfer process that does not require the presence of molecules to transfer heat?
Radiation is the energy transfer process that does not require the presence of molecules to transfer heat. It can occur through empty space and does not require a medium to carry the heat. Examples include heat transfer from the sun to the Earth and infrared radiation emitted by objects.
What is it called when there is a transfer of heat through space without molecules?
The transfer of heat through space without the need for molecules is called radiation. Radiation is a form of energy transfer that does not require a medium to propagate and can occur through vacuum.
Is Convection is the flow of heat energy direct contact between molecules?
Convection is the transfer of heat through the movement of fluids or gases. It does not require direct contact between molecules, as the heat energy is carried by the movement of the fluid itself.
Heat from the sun reaches you by which form of heat transfer?
Heat from the sun reaches you primarily through radiation, as it travels through space in the form of electromagnetic waves. Radiation does not require a medium to transfer heat and can travel through vacuum.
Which heat transfer doesnt need a medium to move through?
Radiation is a form of heat transfer that does not require a medium to move through. It can occur through empty space, such as the heat from the sun reaching Earth through the vacuum of space.

What method of heat does not require matter?
heat transfer
How does the density of the molecules affect heat transfer?
The density of molecules affects heat transfer by determining how closely packed the molecules are. Higher density means more molecules per unit volume, leading to more efficient heat conduction. Lower density results in slower heat transfer due to fewer molecules available for heat energy to be transferred through.
What is the transfer of heat by the movement of molecules which carry the heat?
Conduction.
What type of heat transfer involves molecules bumping into each other?
Conduction involves the transfer of heat through direct contact between molecules, where the molecules bump into each other and transfer kinetic energy.
Why the vacuum between the glass walls of the flask reduces heat transfer by conduction and convection?
In order for heat to transfer by convection, there has to be air or water in order for the molecules to move from place to place. So both these heat transfer techniques require a medium of some sort. In a vacuum, there's no particles at all, so there is no medium present in order for these heat transfers to apply.
What is the transfer of energy by heat caused by the collision of molecules?
When molecules collide and there is a transfer of energy as heat, this is called conduction. When fluids of different temperatures transfer energy by movement, this is called convection.
Why do water molecules retain heat energy?
Water molecules retain energy due to heat transfer.
