Liquids and phase changes

Today we talked about some properties of liquids that can be explained using intermolecular forces including viscosity, surface tension, capillary action and vapor pressure. We then moved to phase transitions and looked at how a heating/cooling curve could be used to understand how much energy in transferred as heat is added or removed from a substance.

There is a new Mastering Chemistry assignment posted, due Monday. My web page is back up so you should be able to access all the information found there, please let me know if there are broken links or missing files.

See you all on Friday.
