Oxygen By: Won 7.2 Subject: Science

Who and When discovered the oxygen? Joseph and Carl Wilhelm, they both independently discovered oxygen. On 1774

Melting point and boiling point Melting point= 54.8 Boiling point= 90.19

3 interesting Facts Solid and liquid are pale blue Gas is colorless, odorless and tasteless It is non-metal

3 uses of oxygen Oxygen is also used in some medicines to treat respiratory disease. It is part of the ozone layers which helps protect us from the ultra violet rays of sunlight. It is used in many of the Steele industries for this purpose.

Pictures of Oxygen

Brief description By depleting atmosphere oxygen levels to very low levels using reactive oxygen scavengers within an impermeable enclosure, a modified atmosphere composed almost for nitrogen can be created.
