Properties of Liquids
1. Define viscosity and surface tension.
2. Explain the relationship of viscosity and surface tension to intermolecular forces.
3. Describe some of the usual properties of water and relate those properties to hydrogen bonding.

Notes: (14-2)The phase of any substance is determined by the inter and intramolecular forces.
Viscosity is a term used to describe the fluid friction (resistance to flow) within a fluid. The amount of viscosity is completely dependant on the amount and strength of the intermolecular bonds.
Surface tension is the downward (toward the middle) force that a fluid exerts on its surface molecules. It is responsible for giving drops their round appearance. The rules governing surface tension are the same as for viscosity.
