The hydrogen bonds between water molecules are the reason behind two of water's unique properties: cohesion and adhesion.
Water is often known as the universal solvent, which means that many substances dissolve in it. Substances that can dissolve in water are hydrophilic. This means that they are as strong or stronger than water's cohesive forces. Salt and sugar are both polar, like water, so they dissolve very well in it. Substances that do not dissolve in water are hydrophobic like saying "oil and water don't mix." Basically people oil is non-poler so a polar substance like water can't mix.
Properties of Water!
Cohesion is when water sticks to itself very easily. Surface Tension is caused by this because water is most likely by itself . When there is more water being left alone by itself the surface tension becomes stronger. In the ocean the water is vast, and there is more water than the water touching the surface so the tension is strong. Doing a bellyflop would hurt because instead of diving down straight your body is all over the place.
Adhesion means that water sticks very well to other things. Adhesion spreads out in a thin film on certain surfaces like glass. If water didn't have Adhesion and I pour the water to the ground it would not soak into the ground and spread. It'll look more like jelly. Without Adhesive there would be no such thing as plants and us. Capillary Action is caused because of Adhesion. When the water is in contact with the roots of a plant it gets collected through the roots and goes upwards.~ When water comes into contact with these surfaces, the adhesive forces are stronger than the cohesive forces. Instead of sticking together in a ball, it spreads out.
Water's boiling point is a property that occurs when water has reached its maximum heat state (100 Degees Celcius)that it turns to into gas vapor if it gets any hotter. Cooking noodles would be an example of heating water because of course it would make the noodles softer to eat. As the water boils you would start to see steam which is the gas because the water came to its boiling point.
Ice melts at 0 degrees celcius. Anything below that is it's freezing point. If I heat the piece of ice slowly it turns into liquid water at 0 degrees celcius. The reason you see ice cubes floating around in warmer water or other liquids is that the heat must be transported from the warmer liquid to the ice for it to melt and in the real world this takes time.
