The cooler denser fluid sinks to the bottom of the pan, where it gets heated by the heat source. As it heats up, it becomes less dense and rises to the top, creating a loop of circulating fluid known as a convection current.
convection
This is known as convection, which occurs when a fluid is heated, becoming less dense and rising, then cooling, becoming denser and sinking. This circular motion transfers heat energy throughout the fluid, contributing to processes such as weather patterns and ocean currents.
Convection currents cause the transfer of thermal energy in fluids. As the fluid is heated, it becomes less dense and rises, while cooler, denser fluid sinks. This creates a circular flow of motion that helps distribute heat throughout the fluid.
The liquid or gas which transfers the heat can circulate round and round between the hot and cold regions. The flow of liquid or gas is called a convection current. Convection currents are caused by changes in density.

A convection current, however, this can also occur with gases.
When part of a fluid is heated, it becomes less dense and rises, creating a convection current. As it rises, it displaces cooler, denser fluid, which then descends to replace the rising fluid. This continuous circulation results in a convection current within the fluid.
Convection current is a stream of fluid propelled by thermal convection. Convection is mostly around gas and liquid
In a convection current, warm fluid rises due to its lower density and is replaced by cooler fluid. As the warm fluid rises, it transfers heat to the cooler surroundings, leading to circulation and the formation of a convection current.
Yes, a convection current is a process in which heat is transferred through a fluid (liquid or gas) by the movement of the fluid itself. This movement occurs because warmer fluid is less dense and rises, while cooler fluid is more dense and sinks, creating a circular flow that transfers heat.
... move to the bottom of the fluid
Heat plays a critical role in convection currents by causing fluid to expand and become less dense. This hot fluid rises, creating a current, while cooler fluid moves in to replace it. This cycle of rising and falling fluid creates the convection current movement.
This circular flow is called a convection current. It occurs when warmer fluid rises and displaces colder fluid, creating a continuous circulation pattern. Convection currents play a key role in various natural phenomena, such as ocean currents and atmospheric circulation.
That is called a convection current. It occurs when warmer, less dense fluid rises and displaces cooler, denser fluid, creating a circular flow pattern. This phenomenon is commonly observed in the Earth's atmosphere and oceans, as well as in other natural systems.
A convection current is a natural flow or circulation of fluid due to a variation in its density due to temperature differences. As a fluid's temperature increases, its density reduces, and the fluid rises to be replaced by fluid at a lower temperature. Convection, together with conduction and radiation, is a method of heat transfer.
the form of energy would be heat. convection currents are caused by uneven heating of air or fluid. The warmer fluid is more boyant than the cooler fluid, so it floats to the top, and creates a "convection current"
