For reasons discussed in the previous section, being less dense than the surrounding cooler air, the hot air will subsequently rise due to buoyant forces - this movement of hot air into a cooler region is then said to transfer heat by convection. ... Figure 8.3: Convection currents in boiling water...

Convection in the most general terms refers to the movement of molecules within fluids (i.e. liquids, gases and rheids). Convection is one of the major modes of heat transfer and mass transfer. In fl...

In this two-part activity, students will observe convective currents in water and observe the air as a fluid. ... Convection currents are found in many places and on many scales, from huge convection currents in the atmosphere, oceans, and even in the earth's interior to smaller convection currents found in a cup of hot...

Wind patterns are large scale convection currents in the atmosphere. If there is a warmer spot on Earth, convection currents are set up resulting in wind as the air circulates. Ocean currents are the same effect but in the water rather than the atmosphere.

It's a typical convection pattern that you can 'see' because the shower curtain is there to make the air movement visible. When you first turn the shower on there may also be a little lift (toward the shower stall) developed on the shower curtain due to the upward movement of the warm air over the surface of the curtain.

A mounting bracket assembly for electronic instrument mounting which also provides for heat dissipation and environmental protection. ... Further, since the mounting bracket assembly is in direct contact with the natural convection air currents, it will be heated as well, and will thus provide additional surface area to...

Air currents driven by the sun's heat cause weather. Warmed air rises from hot equatorial regions and sinks over cool polar seas and ice caps. These convection currents produce differences in air pressure, which cause large-scale movement of the atmosphere.

Convection currents, which represent the vertical movement of warm air upward and cool air downward due to the uneven heating of the earth’s surfaces, and convection, are important mechanisms of heat transfer.
