Name four unique physical properties of water?

Answer 1

1. Cohesion: is the sticking together of similar molecules. Water is very cohesive. This allows water to be pulled along a pathway with relative ease.

2. Surface Tension: cohesion allows water to pull together and form droplets or form an interface between it and other surfaces. The measure of how hard it is to break this interface is its surface tension.

Water allows materials to rest upon it if the surface tension is not broken. Pollen, dust, water insects, and other biological materials are able to remain on the surface of the water because of this tension.

3. Adhesion: The sticking of one substance to another. Water is a good adhesive. It will cling on to many objects and act as a glue. Capillary Action is an example of cohesion and adhesion working together to move water up a thin tube.

4. Imbibition: The process of soaking into a hydrophilic substance. Water being taken into a sponge, into a seed, into paper towels.

Answer 2

1. High specific heat capacity: Water can absorb and release a large amount of heat before its temperature changes significantly.
2. Density anomaly: Water is most dense at 4 degrees Celsius, resulting in ice floating on water.
3. High surface tension: Water molecules are strongly attracted to each other, forming a "skin" on the surface that resists external forces.
4. Universal solvent: Water can dissolve a wide variety of substances due to its polarity and ability to form hydrogen bonds.
