Biophysical forces in molecular systems

1 Scuba divers will often inflate an inflexible canvas buoy underwater with gas released from their low pressure regulator mouthpiece and allow it to float to the surface in order to mark their region of ascent. A canvas bag of 3 1 volume is inflated with gas bubbled into it at 60 ft below the surface. 

2 A new company sells a scuba marker buoy that is much smaller to carry because it has a highly flexible and elastic wall. A dive master on a similar dive to the one in problem Q.6.1 inflates the flexible buoy to 2 1 using the high pressure hose from her gas cylinder. She attaches the buoy to a line and lets it go to the surface. The temperature at 60 ft is 15°C 

3 The instructions for the new flexible buoy are emphatic that the volume at maximum capacity is 10 1. Beyond this volume the buoy will burst. A diver at 60 ft., where it is 15°C, fills the buoy with 4.21 air and releases it. A short time later, the line that had been rising with the buoy goes limp and falls back to the diver with the broken buoy.
