[QUOTE="white92coupe, post: 2907950, member: 1707"] I'm thinking you are the one who is confused about vacuum. The definition of vacuum is a space devoid of matter from Webster dictionary, but is also defined by having a pressure less than atmospheric. There are varying degrees within 1atm and a "perfect vacuum". Vacuum is not a binary yes/no or 1/0 function. If it was we would not have measures from 0-~30 inches of mercury for describing them. Here is some reference material for you. [URL]http://www.engineeringtoolbox.com/vacuum-d_837.html[/URL] [/QUOTE]
