Physical Properties of Ozone
Ozone absorbs radiation firmly in the ultraviolet region of the atmospheric spectrum between 220-290 nm. This protects the Earth and its inhabitants from the harmful ultraviolet radiation of the Sun. Without this Protective layer, increasingly ultraviolet radiation would reach the outside of the Earth and cause harm to the plant, creature and human life.
Pure ozone is a blue gas, with a strong irritating smell. Whenever breathed in, it causes a headache and nausea. In smaller proportions, it smells Pleasant.
It is about 1.5 times heavier than air and has a vapor density of 24, corresponding to the formula O3.
It is more soluble than oxygen in the water, about 49% by volume at 0째C.
It gets liquefied to a deep blue color liquid when cooled in liquid air.
It boils at 161.2 K and solidifies to violet-dark crystals, which melt at 80.6 K.
It dissolves readily in turpentine oil and acetic acid.
