Question

Account for the following (a) the temperature of water

Answer 1

A property that is unique to water versus other substances is that it is most dense at 4 degrees Celsius, or 39 degrees Fahrenheit, and is less dense at either higher or lower temperatures. Most other substances continue to become denser as their temperature drops. Water at higher or lower temperatures will float on top of water that is 4 degrees C. Because ice is less dense than the underlying water, it floats, insulating the warmer water below. Without this unique property, life on Earth would probably not exist.

Hope it helps!!!
