Hi. After watching this short youtube video of a nitro piston air gun . Can someone tell me how compressing a piston filled or partly filled with nitrogen ,how this can force the piston forward to force the pellet out of the barrel once the piston is released from its compresses state .Is there some type of heat being generated when the piston expands to the uncompressed state. http://youtu.be/b741fQL8BRU Thanks in advance.
