What property of water allows fish to survive in freezing temperatures?
And that means fish must be able to survive down here. This is due to a special property of water: the elasticity of H2O. We know that when the temperature sinks below freezing, water first contracts and then expands as it begins to turn to ice. Ice, being lighter than water, floats.
What property of water allows fish to survive in a lake that is frozen over 3 points?
