Heat Transfer
Article about the heat transfer. It is a discipline of thermal engineering that concerns the transfer of thermal energy from one physical system to another. Heat transfer is classified into various mechanisms, such as heat conduction, convection, thermal radiation, and phase-change transfer. Engineers also consider the transfer of mass of differing chemical species, either cold or hot, to achieve heat transfer.

Modes of Heat Transfer
Article about a lecture on modes of heat transfer. Heat transfer is most efficient by convection, then by conduction; radiation is the least efficient and slowest means of heat transfer. Low efficiency of heat transfer means that vacuums make excellent insulation.

Heat Transfer
An article that gives a better understanding on the methods of heat exchange in the atmosphere to appreciate how the thin atmosphere keeps us alive. The driving force for atmospheric motion is the sun and, in particular, the uneven distribution of solar radiation across the earth. It is the primary job of the atmosphere to redistribute energy in order to achieve a balance from pole to equator.

Bill Nye The Science Guy on Heat (Full Clip)
2 min 6 sec musical video about heat transfer. Heat flows. It's the energy of moving molecules. Heat makes things go; it can make things burn. From snow to ice floe, things may look cold, but they've got heat. Conduction, radiation, convection, natural & forced that's how heat gets around.

Convection
1 min 13 sec video lecture on convection. Convection is the movement of warm particles within fluids. Convection is often found in the air as heated air rises and cool air falls. This is because hot molecules spread apart, making them less dense and causing them to rise. Convection is also found in the ocean as currents of different temperatures travel and interact.

Conduction
Video length: 2 min 5 sec. Video lecture on conduction. Conduction is a type of thermal energy transfer involving direct contact. The more tightly packed the molecules within a substance are, the more conductive the substance is.
