We call the flow of thermal energy from warmer matter to cooler matter heat transfer, and we study this in thermodynamics. A link can be found below to check facts and learn more.
conduction = Transfer of Heat WITHOUT Movementconvection = Transfer of Heat Within or Using a Liquid
Convection
conduction because it heats everything
convection current
A convection current, however, this can also occur with gases.

A convection current flows in a circular pattern, with warmer material rising and cooler material sinking (due to density differences). It should not be used with conveNtional current in electricty.
Thermodynamics, which means, basically, "heat movement".
Yes. Heat flows from a warmer to a cooler substance. The technical term is: The Second Law of Thermodynamics.
Heat always flows from warmer objects to cooler objects, unless you have a device (like a heat pump) to prevent this. The natural tendency is for two or more objects at different temperatures to eventually all have the same temperature and this is accomplished by heat flowing from the warmer objects to the cooler objects.
energy alwayy flow from high density to low density
