Oxygen (O2) - colorless gas without taste and smell. It is a little heavier than air: the weight of 1 l of oxygen is under normal conditions equal to 1,43 g, and 1 l of air of 1,293 g. Let's dissolve in water, though in small kolichestvakh:100 water volumes at 0ºС dissolve 4,9, and at 20ºС-3,1 oxygen volume. Boiling temperature - minus 183,0ºС, melting temperature - minus 218,8ºС. Density P at 200ºС makes 1061,45 mg/m3. Oxygen forms the diatomic molecules which are characterized by high durability: standard enthalpy
to atomization of oxygen it is equal 498 kJ/mol. At the room temperature its dissociation on atoms is insignificant; only at 1500ºС it becomes noticeable.
Liquid oxygen has no smell, on color blue also boils at - 183ºС. One liter of liquid oxygen gives about 840 liters of gaseous oxygen.
