  18. Zip a sandwich bag nearly closed. Insert a straw into the opening and blow through the straw to inflate the bag so that it is a little over half full of air. Completely seal the bag. Now slowly roll the zipper part of the bag toward the bottom of the bag, decreasing the volume of the bag. Describe what happens to the pressure of the air in the bag as you decrease its volume. __________________________________________________________________________________
