Convection is the flow of heat energy from a region of high temperature to a region of low temperature by movement of a fluid. Convection only occurs in fluids - liquids and gases.

Heat transfer by convection varies from situation to situation (upon the fluid flow conditions), and it is frequently coupled with the mode of fluid flow. In practice, analysis of heat transfer by convection is treated empirically (by direct observation).

The methods of Heat Transfer section on Boundless covers conduction, convection and radiation. The Heat Transfer section of Hyperphysics also has their usual brand of concise information. Physic Classroom's section which covers heat transfer methods. This site gives a fairly compact view of heat transfer. Other Resources

The three types of heat transfer are conduction, convection, and radiation. Heat transfer occurs when thermal energy moves from one place to another. Atoms and molecules inherently have kinetic and thermal energy, so all matter participates in heat transfer.

Convection is heat transfer by the macroscopic movement of mass. Convection can be natural or forced and generally transfers thermal energy faster than conduction. The table gives wind-chill factors, indicating that moving air has the same chilling effect of much colder stationary air.

Once conducted to the inside, heat transfer to other parts of the pot is mostly by convection. The hotter water expands, decreases in density, and rises to transfer heat to other regions of the water, while colder water sinks to the bottom. This process keeps repeating.
