|
|
|
The fact that water is non polar makes it unable to interact with other molecules causing water to be very stable
|
|
|
The ability of water to be attracted to substances other than itself allows for transport of water in plants.
|
|
|
Water contracts when it freezes, allowing a level of protection to life in a frozen lake or pond.
|
|
|
Water absorbs a large quantity of heat and changes temperature rapidly.
|
Detailed explanation-1: -Discussion of the properties of water that make it essential to life as we know it: polarity, “universal” solvent, high heat capacity, high heat of vaporization, cohesion, adhesion and lower density when frozen.
Detailed explanation-2: -Cohesion is what we call the ability of water to attract other water molecules. It is one of its most important properties. Water has a high polarity, and it gives it the ability to being attracted to other water molecules. These molecules are held together by the hydrogen bonds in water.
Detailed explanation-3: -The four unique properties of water that make it unique are high specific heat, high polarity, adhesion cohesion, and a lower density as a solid. Water having a high specific heat allows it to absorb heat energy without a subsequent change in temperature.
