Conduction is the process of heat transfer through direct contact between two objects or substances. When heat is transferred through conduction, no physical space is required between the objects involved in the transfer. The heat energy moves from the hotter object to the cooler one.

Does heat travel through empty space by conduction?
No, heat does not travel through empty space by conduction because conduction requires particles to transfer heat energy from one molecule to another. In empty space, heat transfer occurs through radiation, where energy is transferred via electromagnetic waves.
Does the energy move from earths surface and atmosphere out of space through radiation conduction or convection?
The energy from Earth's surface and atmosphere moves out into space primarily through radiation. Conduction and convection play a smaller role in transferring heat energy to space.
Why can heat travel through space by radiation but not by conduction or convection?
Heat travels through space by radiation because electromagnetic waves can propagate in a vacuum. In contrast, conduction and convection require a medium like a solid, liquid, or gas to transfer heat through collisions or circulation of particles. Since there is no medium in space, conduction and convection cannot occur.
Why cant energy travel by conduction through empty space?
Conduction requires the presence of matter. The way conduction works, one atom or molecule bumps into another one, transferring heat energy.
Why can't a condution occur in a space?
Conduction requires particles to physically touch to transfer heat. In a vacuum (like outer space), there aren't enough particles for conduction to happen efficiently. Heat transfer in space primarily occurs through radiation, where electromagnetic waves carry heat energy.
