Describe the anomalous thermal expansion property of water and its significance .
Temperature Near freezing , water has a negative expansion coefficient which means it expands as it cools and freezes . Since ice is less dense than liquid water , it floats and stays on top of lakes and oceans . This has allowed aquatic life to survive UNDER the ice even during very cold times .Temperature Near freezing , water has a positive expansion coefficient which means it expands as it cools and freezes . Since ice is more dense than the liquid water , it floats and stays on top of lakes and oceans . This has allowed aquatic life to survive UNDER the ice even during very cold times .
