convection
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.
Convection is "the transfer of heat through the motion of molecules in a fluid."
Convection is the heat transfer process that depends on the movement of air. In convection, heat is transferred through the movement of air molecules as they carry thermal energy from one place to another. This process can occur naturally through the movement of air currents or can be created artificially through mechanisms like fans or ventilation systems.
No, convection is the transfer of heat energy through the movement of fluids (liquids or gases) due to their different densities. This process involves the physical movement of the fluid to carry heat from one place to another.
The term for heat transfer due to the movement of a gas is convection. In this process, heat is transferred through the movement of the gas molecules from one place to another.
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.
The movement of heat without matter to carry it is called radiation. Radiation is the transfer of heat energy in the form of electromagnetic waves, such as infrared radiation from the sun to Earth.
Convection.
Heat can be transferred in a liquid or gas through conduction, convection, or radiation. Conduction is the transfer of heat through direct contact between molecules. Convection involves the movement of the heated material itself, causing a transfer of heat. Radiation is the transfer of heat through electromagnetic waves.
