You are probably thinking of convection, which is transfer of heat by currents set up by variations in density of the liquid.
Conduction
Convection
COnvection
heat moves through liquid by convection. Cold liquid with a higher density is pulled to the bottom of a pot by gravity forcing hot water to the top. As it does this they mix and the cold water is warmed by the hot water.
when an electron moves from low energy state to high energy state , it gains energy.
When a substance moves from an area of low concentration to an area of high concentration while using energy the process is called active transport.
As energy is absorbed, the energy moves up to other electron shell levels, but as the energy is released, it goes back to zero (ground state) and the energy is given off as light.
Osmosis is the diffraction of water through a permeable membrane using no energy, whereas active transport is the moving of particles across a membrane against a concentration gradient. Basically, Osmosis moves water with no energy. Active transport moves particles, in general, with the use of chemical energy like ATP.
Heat passes through liquid and gases through the process called convection. In solids however it passes through the process of conduction.
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.
It is electromagnetic radiation.

Viscosity of the liquid
By convection
That's called a "wave".
Electricity moves through wires.
energy move through forces
passive transport
