A deep lake is cooled by cold air at the surface and a thin sheet of ice has just started to form on top. Find the temperature in C of the water at the bottom of the lake (whole number).
Answer:
4
Solution:
Water is densest at C. Convection currents carry the cooling surface water down until the whole lake is at C. The surface layer then cools below C, becomes lighter and freezes. The bottom stays at C.
