Question

Which of the following represents the correct diagram for anomalous expansion of water as a real life application?

• A. C
• B. D
• C. A
• D. B

Answer 1

The correct option is A

C

During winter season, top layer of water in a lake contracts and forms thick layer of ice and sinks to the bottom. This process will continue till water in a pond reaches its maximum density at 4 ${}^{\circ }$C. When the temperature falls further, the top layer expands, and freezes. This is the situation where, the top layer is frozen, and the water at the bottom of the lake is at 4 ${}^{\circ }$C.
