The water temperature at the surface of a deep lake is 2^ C . What is the expected temperature at the bottom?

Step-by-step solution

Water exhibits anomalous expansion, having its maximum density at 4^ C . In a deep lake, the densest water sinks and settles at the bottom. When the surface temperature drops below 4^ C (such as 2^ C ), the water becomes less dense and remains at the surface. Therefore, the water at the bottom of the lake remains at 4^ C .
