Section 8: Complete questions 1-5 on page 426 of your textbook.
Sections 9-11: Complete the worksheet you got today in class.
Notes to help you with your homework -
All: If you want some extra credit, read this and write me a short reflection on it...Monday Funday news at its finest! http://www.nytimes.com/2013/03/22/science/space/planck-satellite-shows-image-of-infant-universe.html?ref=science&_r=0
Sections 9-11: Complete the worksheet you got today in class.
Notes to help you with your homework -
- A SATURATED solution has dissolved the maximum amount of solute. Graphically, this is on or above the solubility curve line for a given solute.
- An UNSATURATED solution has less than the maximum amount of solute dissolved. Graphically, this is below the solubility curve line for a given solute.
- Here's a video that you should watch:
- Remember, the powerpoint for this unit is at the bottom of the webpage!

Hey guys, after asking my homeroom students, the consensus seems to be that you guys would like more practice problems with the gas laws. The link below is a great worksheet and it has a good answer key so you can see how you're doing.
Mixed Gas Laws Practice
I suggest giving the problems a try before looking at the answer key. We will have a quiz on this stuff soon and you want to know where you're at/what kind of questions you have.

Gents,
I'm sorry I couldn't be with you again today. I should be well enough by tomorrow to return.
If you have not already, please watch the videos posted yesterday.
Then, using the phet simulator link below, complete the worksheet found in the 'Homework Documents' section.
http://phet.colorado.edu/en/simulation/gas-properties
Good luck.

Friday, March 8
Sections 9 & 10: Based on the videos and what we did today in class, answer the following questions:
1) Come up with at least 5 examples of situations that you have witnessed in everyday life, which validate the properties described in these gas laws.
2) Now that you have three equations that relate pressure vs. volume, pressure vs. temperature and volume vs. temperature, see if you can create one equation that involves all three variables.
3) But wait! There's a flaw in your equation! There's a quantity missing that is keeping these equation from being sound for all types of gases. What is it??? (hint: think about a universal form of measurement we use in chemistry).
4) If you can figure out the answer to #3, give the equation another shot, but this time, include your new variable.
Then, write a short explanation for how the egg got sucked into the flask.

5) Critical Pressure
Then use those definitions to complete the worksheet at the bottom of the webpage.
Section 9: Using the phase diagram for CO2 below to answer the following questions:
- At what temperature and pressure is the triple point for CO2
- Describe all the phase changes that would occur when CO2 is heated from 200 K to 350 K at a constant pressure of 10 bar
- Describe all the phase changes that would occur when CO2 pressure is dropped from 100 bar to 1 bar at a constant temperature of 350 K.
- Do some research on supercritical fluid CO2. What is it? How is it used? Does only CO2 have this phase?
