When smoke goes up through a tube to a container and into fire.
A convection current, however, this can also occur with gases.
Toasters primarily use radiation to heat up the bread. The heating element inside the toaster emits infrared radiation that transfers heat to the bread, causing it to toast. Some heat convection may occur as well, as the hot air circulates within the toaster chamber.
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.
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.
Energy cannot escape by convection because convection is the transfer of heat through the movement of fluid particles like air or water. It requires a medium to transfer heat, so in a vacuum or space where there is no medium, convection cannot occur.

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
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.
They occur when the convection currents are less dense and rise.
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.
A chamber summons is when a judge orders for a party's appearance. Chamber summons generally occur on the same day.
