You are probably thinking of convection, which is transfer of heat by currents set up by variations in density of the liquid.

You are probably thinking of convection, which is transfer of heat by currents set up by variations in density of the liquid.
The movement of heat through a liquid or gas is called convection. It occurs through the circulation of the fluid as warmer, less dense regions rise and cooler, denser regions sink, creating a continuous flow that transfers heat.
Heat moves through liquids and gases primarily through convection. This process involves the transfer of heat energy through the movement of the molecules within the substance. As the substance is heated, the molecules gain energy and move around, carrying heat from one area to another. Additionally, in liquids and gases, heat can also be transferred through conduction and radiation, but convection is the dominant mechanism.

Convection
Heat moves through a process called conduction, convection, or radiation. In conduction, heat is transferred through direct contact. In convection, heat is transferred through the movement of fluids like air or water. In radiation, heat is transferred through electromagnetic waves.
This process is called convection. It occurs when heat is transferred through a fluid (liquid or gas) by the actual movement of the fluid itself, carrying heat from one place to another. Convection is a key mechanism for heat transfer in liquids and gases.
Convection, where the heat warms the liquid and this warmer part changes places with the colder part. Also conduction, where the heat moves from one part of the liquid to another.
You can use heat to change a liquid into a gas through a process called evaporation or boiling.
Convection occurs when heat is transferred through the movement of a gas or liquid. As the fluid is heated, it becomes less dense and rises, while cooler fluid moves in to take its place. This creates a continuous cycle of heat transfer.
The flow of thermal energy is called heat transfer. It is through the various means of heat transfer that thermal energy moves from one place to another. Heat moves from where it is hot to where it is not. Always. Think it through and it will make perfect sense.
