Thurs-Day 1
AP - we analyzed phase diagrams for two general types of substances - a substance that has a solid phase that is denser than its liquid phase (true for most substances), and a substance that has a liquid phase that is denser than its solid phase (e.g. water, not many other substances).
We looked at the important parts of the phase diagrams, and saw how to construct one from raw data of normal boiling point, normal freezing point, and the triple point (and critical point, if given).
We then began to look at the colligative property formulas.
Our unit(s) exam is on Monday. There are many practice and tutorial files on Edline.
I will likely leave out Raoult's Law on the next exam because we have enough to do with all of the other question types.
Bio - we reviewed the digestive system worksheet, and then we discussed the causes and symptoms of major diseases/disorders of the digestive system. In 10/11, we did the amylase hydrolysis of starch (in a pretzel) lab.
