Convection

Vedclass · Answer

(B) The mode of heat transfer that requires gravitation is $Convection$. In $Convection$,heat is transferred by the actual movement of fluid particles (liquids or gases). This movement occurs because of the difference in density caused by temperature variations. Warmer fluid becomes less dense and rises,while cooler,denser fluid sinks due to the force of gravity. Without gravity,there would be no buoyancy force to drive this circulation,and thus $Convection$ would not occur.
