At what temperature does gas escape faster? Cold, room temp or warm?

I bought this book through the scholastic classroom book order program. It is a great book and this is just one of the great science experiments that you will find in this book.
What you will need:
3 bottles of soft drinks - we chose 7-Up so that we could drink them after the experiment.
3 identical balloons
1 large bowl

Put 1 bottle in the refrigerator overnight. Leave the other 2 bottles out at room temperature overnight.
We opened the bottle that was in refrigerator and placed a pink balloon over the opening.  We talked about the carbon dioxide creating the bubbles.
Next we opened one of the bottles at room temperature and placed a purple balloon over the opening.
Right away we started to see the balloon fill with air.
Next, we filled a bowl with a couple of inches of hot water.  We placed the second room temperature bottle in the bowl of hot water, opened it and placed a orange balloon over the opening.
We checked on the balloon with the room temperature soft drink. It was filling up faster than the balloon with the bottle that was in the refrigerator.
We compared the three balloons.
The pink balloon on the left, was on the bottle out of the refrigerator.
Orange balloon in the middle, was on the bottle that was in warm water.
Purple balloon on the right, was on the room temperature bottle.
You can already tell that the orange balloon was filling up faster than the other two.

Fifteen minutes later, The orange balloon was the fullest. The answer to the question "What temperature does gas escapes faster?" warm gas.

I hope that you have as much fun with the experiment as we did.

Here is a list of the Linky parties that I link up to.  Thank you to all of the hosts for letting me post my favorite recipes, crafts, money saving ideas and activities for children.
