Hydrogen bonding. Water molecules electrons are not sharred evenly between the hydrogen and oxygen atoms. The easiest way to explain it is that the oxygen atom "hogs" the electrons. Since it has 8 protons in it's nucleus the oxygen has a greater pull. Hence the oxygen is slightly negative (negative charge of electrons) and ther hydrogen side has a slightly positive charge. Hydrogen bonding is part of the category known as Van Der Wall forces. Basically, the hydrogen part of the water molecule bonds with a slightly negative part of another molecule. This allows for adhesive and cohesive bonding cababilities of water.

Why is polarity important?
The behavior and properties of chemical compounds depend also on the polarity of their molecules. Typical examples are the solubility or intermolecular associations.
Describe the polarity of alkane molecules?
Alkane molecules are nonpolar.
How does the polarity of a substance affect how far it travels up the chalk?
because there is polarity of molecules in there
Which characteristic of water molecules makes water a good solvent?
The polarity of water results in the ability of water to dissolve other hydrophilic molecules
What type of bond results between water molecules due to water's polarity?
Hydrogen bonds form between water molecules due to water's polarity.
Why is polarity important?

How does the existence of polarity within a molecule lead to its ability to dissolve?
Water has a polar molecule; attraction between electrically charged parts of molecules is the cause of solubility.
What property do water and hydrophilic molecules share?
Both are polar. Explaining chemical polarity kind of surpasses the scope of this question.
What give water special properties such as cohesion?
Hydrogen bond
Describe the polarity of alkane molecules?
Alkane molecules are nonpolar.

Which characteristic of water molecules makes water a good solvent?
The polarity of water results in the ability of water to dissolve other hydrophilic molecules
Is H2O ionic polar or non polar?
H2O is polar because of the two hydrogen molecules being attracted to the hydrogen molecule and water is a universal solvent which means it can dissolve solutions and has polarity.
What type of bond results between water molecules due to water's polarity?
Hydrogen bonds form between water molecules due to water's polarity.
What are spheres of hydration?
When solutes are dissolved in water, many water molecules cluster areound each solute molecule(attracted by polarity) This keeps the solute dispersed in the fluid. The water molecules in these "spheres" are tied up and not free to cross a water permeable membrane.
What is A magnet erasing a computer disk is that a physical or chemical?
Magnetic erasing of a computer disk is a physical change. The polarity of the molecules in the storage media is altered, but the material retains the same composition so it is NOT a chemical change.
What is the surface tension in a cup of water caused by?
The surface tension in a cup of water is caused by attraction. The hydrogen molecules in the water are attracted to the polar oxygen bonds.
