|
|
Water has adhesive properties that lower its freezing point allowing it to stay in liquid form longer.
|
|
|
The density of water changes when it freezes so solid water is less dense than liquid water allowing it to float.
|
|
|
Water has a high boiling point allowing it to evaporate and condense into clouds providing moreliquid precipitation.
|
|
|
The melting and freezing points of water shift based on latitude, allowing it to stay in liquid formlonger in higher latitudes.

Detailed explanation-1: -This means that ice is less dense than liquid water, which is why it floats. This property is important, as it keeps ponds, lakes, and oceans from freezing solid and allows life to continue to thrive under the icy surface.
Detailed explanation-2: -Water’s high heat capacity is one of the major properties that make life under the sea possible.
Detailed explanation-3: -Hydrogen bonds also give water a high latent heat; the heat required to undergo a phase change from solid to liquid, or liquid to gas. The latent heat of fusion is the heat required to go from solid to liquid; 80 cal/g in the case of ice melting to water.
Detailed explanation-4: -The hydrogen bonds between water molecules give water the ability to hold heat better than many other substances. As the temperature rises, the hydrogen bonds between water continually break and reform, allowing for the overall temperature to remain stable, although increased energy is added to the system.
Detailed explanation-5: -Each water molecule can create hydrogen bonds with up to three other water molecules. The strength and number of hydrogen bonds are the reasons behind the unique thermal properties of water.
