What will happens to convection currents when liquid or gas is no longer heated?
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.
Why does the Pangaea supercontinent no longer exist?
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.
Why a pot f water heated from the top takes a long time to boil but boils quickly when it is heated from the bottom?
When a pot of water is heated from the top, the heat must first transfer down through the water before it can reach the bottom layers, resulting in inefficient heat distribution and longer boiling times. In contrast, heating from the bottom allows the heat to directly warm the water at the base, creating convection currents that circulate the warmer water upwards. This efficient transfer of heat accelerates the overall heating process, allowing the water to reach its boiling point more quickly.
How oxygen and nutrients are transported by ocean currents?
By the currents themselves - water contains oxygen (hence H2O), and nutrients, thanks to decaying (biotic) matter which, yes, contains nutrients even when no longer living.
Why is metal no longer magnetic when heated?
When heated, the thermal energy supplied to the metal causes the thermal motion of its atoms to increase, disrupting the alignment of their magnetic moments. This disrupts the collective magnetic behavior that gives the metal its magnetic properties. As a result, the metal loses its magnetism when heated.
Will the convection currents stop flowing if the pot is no longer heated?
It'll stop flowing when all of the material has reached th same temperature.
What will happens to convection currents when liquid or gas is no longer heated?
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.
What happends to convection currents when the liquid or gas is no longer heated?
It falls back down
What happens to convection currents if the heat source is removed?
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.
What happens to convection currents when the liquid or gas is no longer heat?
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.

What happens to convections currents when the liguid or gas is no longer heated?
The conventional currents will continue until the temperature of the substance is equal to surrounding temp.
What happens to convition current when the liquid or gas is no longer heated?
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.
Why does the Pangaea supercontinent no longer exist?
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.
explain how heat transfer can be minimised by convection in a vacuum flask?
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.
Why does the closed lid of thermal mug keeps liquid hotter for longer?
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.
What does the high specific heat of water have to do with the convection currents in the air at the seashore?
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.
