Question

fish are able to live in ponds in the winter time. which of the following special properties of water makes this possible? water is a versatile solvent and can dissolve a variety of materials. water has a high specific heat and resists changes in temperature. water molecules tend to stick to other water molecules through cohesion. water expands when it freezes.

Explanation:

When water freezes, it expands and ice is less dense than liquid water. So ice floats on the surface of the pond, insulating the water below and allowing fish to live in the relatively warmer water beneath the ice layer. The other properties mentioned do not directly relate to fish surviving in winter - water being a solvent, high - specific heat, and cohesion are not the key factors for this phenomenon.

Answer:

Water expands when it freezes.
