Oxygen
Boiling Point: -297.4°F (-183.0°C, 90<sup>o</sup>K)
Freezing Point: -361.9°F (-218.8°C, 54<sup>o</sup>K)
Nitrogen
Boiling Point: -320.5°F (-195.8°C, 77<sup>o</sup>K)
Freezing Point: -346.0°F (-210.0°C, 63<sup>o</sup>K)
Hydrogen
Boiling Point: -423.0°F (-252.8°C, 20<sup>o</sup>K)
Freezing Point: -434.5°F (-259.2°C, 14<sup>o</sup>K)
Helium
