Dissolving Gases in a Liquid
How do you keep the “fizz” in your pop?
Where’s the best place to fish on a hot summer day?
What to keep in mind when you go SCUBA diving?
All of these questions refer to the solubility of gases in liquids.

Temperature
In groups of 2 or 3 discuss how you think temperature effects the solubility of gases in liquids.
Some examples which may help guide your discussions are:
1. Storing a pop bottle in the fridge rather than leaving it on the counter.
2. On a hot summer day where are you more likely to catch fish?
Make a hypothesis on how you believe temperature effects solubility of a gas in a liquid.
In your groups, do a web search to check if your hypothesis is correct. (remember to use creditable sources)

Pressure
Stay in your groups.
Get a bottle of pop from your teacher and answer the following questions:
Question 1: Before opening the bottle, is this a solution?
How do you know?
Question 2: Look on the label. What are the solutes?
Solvent?
Question 3: What type of solution is this?
Question 4: Are the solutes and solvent polar or
non-polar?
Question 5: Open the bottle. Why does the drink make
that sound when you open it?
Enjoy your drink while you finish this lesson.

As before, discuss how you think pressure effects the solubility of gases in a liquid.
Some examples which may help guide your discussions are:
1. The pop bottle exercise from earlier.
2. SCUBA diving - why should scuba divers take their time when coming up to the surface after a deep dive?
(Bends, aka decompression sickness)
Again, in your groups, make a hypothesis on how you believe pressure effects solubility of a gas in a liquid.
Do a web search to check if your hypothesis is correct. (remember to use creditable sources)
