    You're problem description is indefinite. At atmospheric pressure, oxygen liquidifies at 90.20 K (-182.95 °C). This appears to be your starting condition. If you're meaning to say the tank (filled with this liquid oxygen) is sealed and the oxygen will warm, the pressure will indeed rise due to the evaporation of the liquid oxygen to gaseous oxygen. The pressure in your tank can be calculated using the ideal gas law ( http://en.wikipedia.org/wiki/Ideal_gas_law). \[PV=nRT\] So, you're saying a tank is filled with liquid oxygen and closed. The oxygen becomes a gas and the pressure rises. The pressure will be \[P=nRT/V\] n is the number of moles [mol] R is the gas constant 8.314 [J/mol K] T is the temperature of your gas [K] V is the volume [m3] and P is the pressure [Pa] (nb atmospheric pressure (1 atm) = 101325 Pa)
