In convection heat transfer one of the main movers of heat energy is: A. Radiated heat through windows B. Heat transferring through molecule to molecule touching C. Heat that escapes rooms because of poor insulation D. Gravity
In convection heat transfer, the main mover of heat energy is primarily related to the movement of fluids (liquids or gases) and the transfer of heat through the bulk movement of these fluids. Among the options provided, the most relevant choice is:
D. Gravity
Gravity plays a significant role in convection processes, particularly in natural convection, where the movement of fluid is driven by density differences caused by temperature variations. Warmer, less dense fluid rises, while cooler, denser fluid sinks, creating a convective current that facilitates heat transfer.
While options A, B, and C involve heat transfer mechanisms, they do not specifically pertain to convection as the primary mover of
