The reliability of the people giving you the facts is as important as the facts themselves.
Convective heat transfer, often referred to simply as convection, is the transfer of heat from one place to another by the movement of fluids. Convection is usually the dominant form of heat transfer in liquids and gases. Although often discussed as a distinct method of heat transfer, convective heat transfer involves the combined processes of unknown conduction and advection.
HEAT TRANSFER â Heat is passed from HOT/Warmer regions, to COLD/Cooler regions. This happens in 3 waysâ¦ 1. CONDUCTION â when heat is transferred by DIRECT CONTACT of matter particles (touching) 2. CONVECTION â when heat is transferred by the MOVEMENT of a fluid (liquid or gas). 3. RADIATION â when heat is transferred through EMPTY SPACE (in the form of electromagnetic waves) recallâ¦â¦ LITHOSPHERE = The SOLID, RIGID outer portion of the Earth that is composed of the CRUST and
