Ok, I am confused

Thanks AJ. I didn't know there were two different common gas blends but that makes a lot of sense.

In science class we should have been doing keg distribution / balancing word problems with varying gas blends instead of all those boring Boyle's law questions. And in the lab we could test our results.

Anybody else wish A.J. had been your science teacher in high school? Thanks for the lesson!

In college, we played quarters in one of the Physics labs. If A.J. was the professor, I might have passed the course!
