I have a 2 liter plastic coke bottle half filled with water, the other half filled with air. A flexible straw is inserted into the top and the top is then sealed. The end of the straw in the bottle is at the bottom of the bottle in the water and the other end of the straw is over a measuring cup. Here are my questions: 1) Can you show me a formula and an example of how to calculate the amount of water pushed out of the bottle when the temp. of the air inside of the bottle is raised by 10 and 20 deg. C? 2) Does the amount of air in the bottle matter? for example 3/4 air -1/4 water or 1/4 Air 3/4 water?
