Question

what is convection? heat transfer by fluid movement energy being transferred by friction energy being created

Explanation:

Convection is a mode of heat transfer. By definition, convection involves the transfer of heat through the movement of fluids (liquids or gases). The option "energy being transferred by friction" refers to heat transfer by friction (like in some mechanical cases, but not convection), and "energy being created" is incorrect as energy can't be created (law of conservation of energy). So the correct description of convection is heat transfer by fluid movement.

Answer:

heat transfer by fluid movement
