Nitrogen Phase Change?

02/17/2011 9:24 PM

1) What happens with pure Nitrogen if we bring it to 500bar at 20 degC. Is it gas, liquid or solid?

2) What happens after, if we bring it to 170degC at 500bar?

(I couldnt find any phase diagram for Nitrogen)

Thanks to any help or advice!

See some of these links, obtained by Googling "nitrogen phase diagram":
