Ch5 Lec 2

Greetings,

If you look on the webpage, you will see that there is an active link to the Exam 2 on Friday April 3. I suggest you have a look at that link to give you more information about the format of the exam.

Note that the chapter 5 outline was given in Lecture 1. I have chosen to focus our attention on only the first 4 sections of chapter 5.

The following two sections are both discussed in the following Crash Course...please note that these crash course videos provide a huge amount of information in a short time period. This one in particular goes into a lot of the background histroy, which is an important thing to know, but will not be on the exam...have a look at:

Boyle's Law Question

So if you have a container of gas at 1.0 atm pressure (P₁) and 1.0 L volume (V₁)...if the volume is changed to 0.5 L (P₂), then what happens to the pressure?

Use: P₁V₁=P₂V₂;

Answer: 2.0 atm
