We started our study of the Gas Laws. We described Gay-Lussac, Boyle and Charles' Laws. We worked sample problems and discussed the history of how the laws were developed. I said that math applied to science continues to be a challenge for many students, and that when they understood the basics, their minds would be free to study other matters -- that would help them become better students. To help in this, I offered to teach how to make and use the slide rule to multiply and divide, and other math functions used in science. This would be (basically) on-line so it could be studied out of class.
Homework: Select AT LEAST three problems from EACH of the problem groups on page 446 of your text (Holt -- Chemistry) starting with problem 35 and going to problem 51. It would be best if you do all 17 problems, but 9 is acceptable. REMEMBER: that is 3 from Nos. 35 - 40; 3 from 41 - 46 and 3 from 47- 51.
On Monday, 2 August, my students needed to bring their water bottles with the steel wool inside ("In Rust We Trust" experiment). We will check the final volume and weights. My students will then have until Wednesday to hand in the report of the experiment
