You are probably thinking of convection, which is transfer of heat by currents set up by variations in density of the liquid.
Heat (thermal energy) will move between a liquid and a spoon placed in it by the method we call conduction. The thermal energy will be conducted from a hot liquid to a cool spoon by direct contact. There will be a bit of convection in the liquid near the spoon. This is because that liquid (being hotter or cooler than the spoon, depending on the experiment) changes density and either rises or descends. But the point is that direct contact between the liquid and the spoon will set up conditions that allow conduction of the thermal energy.

One that is readily set alight and burns easily, such as petrol or neat alcohol.
Grout is cement, sand & a liquid, the liquid starts the process of the cement & sant setting from a powder to a solid. Traditionally it was WATER that was used as the liquid newer grouts substitute Epoxy as the liquid, making the grout set harder stick together better and resist stains

Heat can move around through conduction, convection and radiation. You're probably referring to convection, since it relies on a fluid like a liquid or a gas in order for a convection current to be set up, but conduction or radiation are both also capable of passing heat through a liquid or gas.
The three factors that set convection currents in motion are: the heating and cooling of fluid, change in its density, and the force of gravity combine to set it in motion.
convection currents are set into motion by heat.without heat the convection currents would stop when all the material reaches the same temperature.

Meiosis is a special type of cell division. It is important to reproduce due to the sets of chromosomes in the cell.

Convection currents are responsible for the movement of heat (and mass) within a fluid system. Heat wants to go from where it is to where it isn't. When atoms and or molecules of a fluid (a gas or liquid, for example) are hotter then their companion particles, they are less dense and rise in the fluid. Cooler, more dense groups of atoms or molecules take their place. Convection currents are thus set up, and heat travels "around" the system via those currents. A link to the Wikipedia article on convection is provided.
Set Cell is used to specify a cell in the worksheet that you want to have a particular value in when the process is finished, by changing a value in another cell. The cell specified in Set Cell will always have a formula in it.
