Oxygen is a gas under normal conditions and so has no hardness or luster.
The melting or freezing point of oxygen at standard temperature and pressure is 54.36 K (−218.79 °C, −361.82 °F)
The density of oxygen gas at standard temperature and pressure is 1.429 g/L. the density of liquid oxygen at its boiling point (−182.962 °C or −297.332 °F) is 1.141 g/cm3.
The atomic weight is about 15.999
Oxygen as a gas has no color. As a liquid it is a light blue.
oxygen does not have luster seeing as it is invisible, it is said to be malleable though.
Density of oxygen is 1.429 (g/cm3)
why is the temperature and the pressure important when giving the density of oxygen and nitrogen
This element is helium with a melting point of -272,20 0C.
Which substance has the highest density at room temperature? hydrogen, oxygen, water
Oxygen is an invisible gas, so it has no metallic luster.

Because of different structure and bonds between oxygen atoms
react with the air, generally oxygen
The melting point (or freezing point) of oxygen is -218,79 0C.
Density of oxygen is 1.429 (g/cm3)
react with the air, generally oxygen
As the altitude increases, the density of oxygen decreases.
The freezing or melting point of oxygen is -218.8 degrees Celsius or 54.36 Kelvin.
why is the temperature and the pressure important when giving the density of oxygen and nitrogen
No, they have very low melting.
