The water on the surface of a lake is just about to freeze. The most likely temperature at the bottom of the lake is
- A \(4^{\circ} \mathrm{C}\)
- B \(0^{\circ} \mathrm{C}\)
- C \(-4^{\circ} \mathrm{C}\)
- D \(-273^{\circ} \mathrm{C}\)
Answer & Solution
Correct Answer
(A) \(4^{\circ} \mathrm{C}\)
Step-by-step Solution
Detailed explanation
The water at the bottom of the lake will have maximum density. The density of water is maximum at \(4^{\circ} \mathrm{C}\). Hence, the temperature at the bottom of the lake is \(4^{\circ} \mathrm{C}\)
