CHM 150 Wk 7 Discussion – Phase Changes

Week 7 Discussion

Here are the discussion topics for the last week. As long as you otherwise meet all participation rules (see my Instructor Policies), you may respond to only Section A or only Section B, or both sections if you so choose.

Initial participation posts less than 200 words will not be considered substantive. Any follow-up posts, or your initial response to a second section, will need to be at least 100 words. Note that when evaluating word limit, only the main response made in your own words is counted, and not any direct quotes, citations, signature, or anything not directly linked to your post. Additionally, any remarks such as agreement, compliments, restatement, numerical analysis, table, chemical formulas and equations, etc., will also not be considered as part of substantive posts.

Due Thursday: Section 1 OR Section 2

Section 1: geckos

Geckos use intermolecular forces to climb a wall. What are some other instances where Mother Nature has used such intermolecular forces?

distillation

Fractional distillation is the process by which a mixture of two or more miscible liquids is separated into its components, due to the difference in their heats of vaporization. What industries make use of this process?
