Question

question 7 10 pts which form of heat flow involves the transfer of heat by buoyant mixing in a fluid? reduction convection conduction radiation

Explanation:

Convection is the heat - transfer mechanism in fluids that occurs due to buoyant mixing. In a fluid, warmer and less - dense regions rise, and cooler and denser regions sink, creating a circulation pattern that transfers heat. Reduction is not a heat - transfer mechanism. Conduction is heat transfer through direct contact, and radiation is heat transfer through electromagnetic waves.

Answer:

B. convection
