  1. I find a diagram like this helps with these questions. Do you see the answer?
    Not to scale.
    101.........H2O gas(steam)
    100.........H2O b.p. liq/gas
    99..........H2O liquid

    20...........room temp H2O liquid
    0..........freezing point H2O liq/solid
    -1.......... H2O solid

    -182............O2 liq? gas?
    -183...............b.p. O2 liq/gas
    -184..............O2 liq? gas?

    -193..............question
    -195 N2 gas
    -196..............b.p. N2 liq/gas
    -197 liq
