What happens to convection currents after the stove is turned off?

Convection currents are the movement of fluid caused by the transfer of heat, where warmer, less dense fluid rises while cooler, denser fluid sinks. When the stove is turned off, the heat source is removed, but the water does not immediately reach thermal equilibrium. This means that the warmer areas of water will still be less dense and continue to rise for a period of time. As they rise, the cooler, denser water moves down to take their place, facilitating continued circulation.

This ongoing movement allows for the transfer of energy throughout the water even after the stove has been turned off. The warm water retains heat for a little while, which maintains some convection currents until the overall temperature of the water begins to equalize and cool down. This process is why the continued transfer of energy through the water occurs after the heat source has ended, confirming that the answer provided accurately reflects the behavior of convection currents during that phase.
