It'll stop flowing when all of the material has reached th same temperature.
If the heat source is removed, convection currents will eventually stop because there is no longer a temperature difference to drive the circulation of the fluid. As the fluid cools down to the surrounding temperature, the convection currents will gradually slow down and dissipate.
Water has a higher specific heat capacity than land, meaning it takes longer to heat up and cool down. Land heats up and cools down more quickly because it has a lower specific heat capacity. Additionally, water can circulate heat more effectively through currents and convection, while land transfers heat mainly through conduction.
whether DUST floats around, I suggest you read about Brownian motion. In a nutshell, it is well-established that particles suspended in a fluid (in this case, dust suspended in air) exhibit constant, random motion. Dust particles will eventually settle to the surface due to gravity, but any disturbance can kick them up again, and particles can remain suspended for very long times (the lighter the particle, the longer it can remain suspended).
Soil tends to hold heat longer than sand due to its higher specific heat capacity and thermal conductivity. This means that soil can absorb and store more heat energy, making it warmer for a longer period compared to sand.
A chemical reaction has ocurred her and it has now formed a compund.
Once the pot is no longer heated, the temperature of the liquid inside will begin to stabilize and the convection currents will gradually slow down and eventually stop as the temperature equalizes throughout the liquid.
When a liquid or gas is no longer heated, the heat source that drives convection currents is removed. As a result, the temperature differential that causes the fluid to circulate diminishes, and eventually the convection currents will slow down and stop as the fluid reaches thermal equilibrium.
It falls back down
If the heat source is removed, convection currents will eventually stop because there is no longer a temperature difference to drive the circulation of the fluid. As the fluid cools down to the surrounding temperature, the convection currents will gradually slow down and dissipate.
Nothing actually happens to convection currents when heat is no longer supplied. The currents are produced by applying heat, most often to the bottom. The warmed fluid is 'lighter' than the cold fluid surrounding so it rises to allow colder fluid to replace it and be heated. As soon as the heat is removed, all the fluid rapidly comes to a single temperature and convevtion does not happen! An opposite effect happens when cold air sits on the surface of a lake. In this case the water at the surface cools, gets 'heavier' and sinks. In this case the convection currents operates downwards.

The conventional currents will continue until the temperature of the substance is equal to surrounding temp.
When the liquid or gas is no longer heated, the convection current slows down or stops completely. This is because the temperature difference that drives the movement of the fluid is no longer there. As a result, the fluid will eventually reach thermal equilibrium where there is no more heat transfer and the convection current will cease.
The Pangaea super-continent no longer exists because it has broken up into the continents that exist today, as a result of continental drift caused by convection currents in the earth's mantle.
Heat transfer by convection can be minimized in a vacuum flask because there is no air (or fluid) inside to carry heat through convection currents. The vacuum creates a barrier that reduces heat transfer by convection, as there is no medium for the heat to move through. This helps to keep the contents of the vacuum flask at their original temperature for a longer period of time.
The closed lid of a thermal mug helps to trap heat and prevent it from escaping, thus maintaining the temperature of the liquid for a longer period. It creates a barrier against heat loss through convection and evaporation, keeping the contents hot.
Water'specific heat capacity is 4200 J/Kg°C . This high specific heat capacity suggests that the water will travel long distances without losing heat . This makes the convection currents in the air last longer.
