Why is oxygen called gas? Give two reasons.

Answer :

Oxygen is a non-metal which is very reactive. It readily forms oxides by reacting with elements.

• Oxygen remains in gaseous state at normal temperature and pressure.

• The particles of oxygen move randomly in all directions due to less inter particular force and high kinetic energy.

• They do not have a fixed shape or volume.

• They have low densities and can be compressed easily. Hence oxygen is called gas.
