Question

Why does the surface of a lake freeze first?​

Answer 1

Answer:

And because the same mass of molecules takes up more space when frozen, ice is less dense than liquid water. For this same reason, water below 4° Celsius becomes increasingly less dense as it gets colder. ... As this layer cools to its freezing point, ice begins to form on the surface of the lake."
