How do the properties of water relate to its polarity?

Answer 1

The polarity of water molecules means that molecules of water will stick to each other. This is called hydrogen bonding.

Polarity makes water a good solvent, gives it the ability to stick to itself (cohesion), stick to other substances (adhesion), and have surface tension (due to hydrogen bonding).

Check out video of a stream of water being bent - a plastic ruler is used in the demo. The stream of water bends due to the polarity of water molecules.

Here is video showing how a paperclip can "float" on water - it's actually being held up by the hydrogen bonds formed between water molecules which give water its surface tension.

Answer 2

Just to add to what mrpauller said:

Water is polar due to the fact that it has a bent tetrahedral molecular geometry thus the dipole moment of the water molecule is not zero, if it is zero then a molecule is non-polar (CO2 is an example) because of the force of pulling due to the hydrogen and lone pairs of electrons.

Because of this water experiences all the properties mentioned by mrpauller.

Answer 3

The properties of water, such as its high surface tension, cohesion, and adhesion, are directly related to its polarity. Water molecules are polar due to the uneven distribution of electrons between oxygen and hydrogen atoms, resulting in a slightly negative charge on the oxygen atom and slightly positive charges on the hydrogen atoms. This polarity allows water molecules to form hydrogen bonds with each other and with other polar molecules, leading to properties like high surface tension, cohesion (water molecules sticking together), and adhesion (water molecules sticking to other substances). These properties are crucial for many biological processes and environmental phenomena.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
