convection

Answer 2

Movement Of Thermal Energy

Answer 3

Convection
Convection is usually the dominant form of heat transfer in liquids and gases. This is a term used to characterize the combined effects of conduction and fluid flow. In convection, enthalpy transfer occurs by the movement of hot or cold portions of the fluid together with heat transfer by conduction. For example, when water is heated on a stove, hot water from the bottom of the pan rises, heating the water at the top of the pan. Two types of convection are commonly distinguished, free convection, in which gravity and buoyancy forces drive the fluid movement, and forced convection, where a fan, stirrer, or other means is used to move the fluid. Buoyant convection is because of the effects of gravity, and hence does not occur in microgravity environments.

Answer 4

Heat Energy moves in three different ways, convection, conduction and radiation. In gases, the primary means of thermal energy transfer is convection. Molecules physically move from one location to another taking their energy with them.

In convection ovens, the air in the oven circulates and the heat flow with it.

In solids energy moves primarily by conduction. All of the molecules are fixed in one location, and the transfer occurs when a hotter molecule touches a cooler molecule, transferring heat. A good example of conduction is when you touch a hot pan with your hand. Heat from the pan transfers by conduction to your hand.

Now if you stick your hand into hot water, both conduction and convection come into play. Direct contact with water molecules would transfer heat, but the cooling of the water caused by your hand would create thermal currents that would evoke convection, moving hot in and cold out.

Radiation is the transfer of heat from an object that is hot to an object that is cold without any contact. The best example of this is the sun heating your body on a beach. The sun is not touching you by it is heating you. Another example is a broiler in an oven. The red hot coil actually transfers heat by radiation directly to the meat you are broiling.

Radiation occurs at all temperatures, but becomes the dominant form of heat transfer when temperatures get very high and the hot material actually will glow.
