Question

The direction shown in figure of convection current is correct.

• A. The direction in warmer water is correct but in cooler water is incorrect
• B. The direction in warmer water is incorrect but in cooler water is correct
• C. Both the direction in warmer water and in cooler water are correct
• D. None of the above

Answer 1

Answer: (C)

As we know that after $4^{o}C$ density of water decreases as temperature of water increases, so when the below part of the container is heated, density of water decreases and due to buoyant force, water with more density (less temperature) descends and water with less density (more temperature) rises up.

So, direction of both warmer and cooler water is correct.
