Liquid oxygen is used in the steel industry, in the chemical industry, in hospitals, as rocket fuel oxidant, and for wastewater treatment as well as in many other applications. A tank sold to hospitals contains 0.0284 m3 of volume filled with 3.500 kg of liquid O2 that will vaporize at 25°C. After all of the O2 in the tank vaporizes, will the pressure in the tank exceed the safety limit for the tank specified as 104 kPa?
