Convection occurs when there is a difference in temperature that causes a fluid (liquid or gas) to move. This movement is driven by the warmer, less dense fluid rising and the cooler, denser fluid sinking. The presence of gravity is also essential for convection to occur.
A convection current, however, this can also occur with gases.
Conduction and convection require a medium to transfer heat, but space is a vacuum so there is no medium for these processes to occur. Radiation, on the other hand, can occur in the vacuum of space because it does not need a medium to transfer heat energy.
Conduction and convection are both methods of heat transfer. They both require a material medium for the transfer to occur - conduction is through direct contact between materials, while convection involves the movement of fluids.
Heat transfer through air can occur through conduction, convection, and radiation. In the case of radiation, heat is transferred through electromagnetic waves without the need for a medium to carry the heat.
No. Convection requires a carrier to convey the heat. Vacuum says there is nothing to do the conveying. Radiation does not need a convector, so heat can travel by radiation through a vacuum, like the radiation from the sun.

Convection
Convection currents are in the liquid and gas states.
mantle
Convection occurs mainly in the gaseous state, where heat is transferred through currents in air. Convection can also occur in liquids, however it is generally identified with gases.gas and liquid
They occur when the convection currents are less dense and rise.
Convection is most likely to occur in fluids, such as liquids or gases, due to the movement of their particles. Additionally, convection can also occur in certain solids that are capable of flowing, such as molten lava or heated metals.
When smoke goes up through a tube to a container and into fire.
Convection currents occur in the mantle, which is the middle layer of the Earth. The heat generated from the core causes the molten rock in the mantle to move in a circular pattern, creating convection currents.
