Show answer & explanation
Correct answer: D
Key idea: Convection is heat transfer in fluids caused by the movement of the fluid itself: warmer fluid becomes less dense and rises while cooler fluid sinks. When hot water is mixed with cold water, the warmer water rises and the cooler water sinks, producing convection currents that circulate and distribute heat through the container.
