Convection is the transfer of heat through the flow of fluids. Both liquids and gases can convect heat. Atoms will flow away from hot regions toward cooler regions, carrying their heat and energy with them. If you’ve ever been in a bath that has started to go cold, and then turn the hot tap on, you’ll feel the hot … See more Conduction is what scientists call the transfer of heat through touching. If you touch something warm, heat goes from it to you. If you touch something cold, heat goes from you to it.

WebRadiation is the transfer of heat through electromagnetic waves through space. Unlike convection or conduction, where energy from gases, liquids, and solids is transferred by the molecules with or without their physical movement, radiation does not need any medium (molecules or atoms). Energy can be transferred by radiation even in a vacuum. WebHeat can be transferred in a vacuum via Radiation. This means that heat energy can travel in forms of electromagnetic waves. Conduction is the process of heat transfer between solids that are in contact with each other.
