If the surface of water in a lake is just going to freeze, then the temperature of water at the bottom is :
A0°C
B4°C
CNone of these
D3°C
Answer:
B. 4°C
Read Explanation:
It would be 4°C . Water achieves its maximum density at roughly 4°C. That is, water (including ice) at all other temperatures below or above 4°C is less dense. Since matter is ordered from top to bottom by increasing density, any 4°C water in a lake will be found at the bottom.
