Hey guys, i was wondering what would the graphs be of various attributes of a container of nitrogen while its being compressed. What would the Pressure graph look like, the volume graph, and the temperature graph look like? I was wondering about how they make liquid nitrogen and what the attributes would be and i came up to a problem. Im thinking "Ok, volume goes down, pressure must increase to make the ideal gas law make sense". Then i realized that liquid nitrogen is... well, really really cold so i was wondering what is actually going on. Thanks for the help in understanding :). *added* Also, if you introduce liquid nitrogen into a vacuum (real world), wouldnt it start evaporating?
