Water Molecule Structures

Non-Polar Covalent

Share electrons equally

Non-Polar Covalent

Share electrons unequally

Hydrogen Bond

Attraction between two polar molecules

Polar Molecule

Molecule where one end is + and the other -

How are H₂O molecules shared?

Polar covalent bonding

Are water molecules polar or non-polar?

Polar

Are hydrogen atoms + or -

Partially positive

Are Oxygen atoms + or -

Partially negative

Cohesion

Water mol. sticking to each other through hydrogen bonding

Adhesion

Water molecules hydrogen bonding to another kind on molecule

Why is water a universal solvent?

• It is very abundant

• Polarity

• (+/-) ends allow it to interact with anything that had a charge

Hydrophobic

Non-Polar molecules are….

Buoyancy

An upward force applied to an object immersed in a fluid

Viscosity

Measure of a fluids tendency to flow

Thermal Conductivity

A measure of a materials ability to move heat

Specific Heat capacity

The quantity needed to raise the temp of a chemical per unit mass
