Answer:
welding. Nitrogen
oxygen to obtain energy to fuel all our living processes
Explanation:
Example Gases
Oxygen (O2): medical use, welding. Nitrogen (N2): fire suppression, provides an inert atmosphere. Helium (He): balloons, medical equipment. Argon (Ar): welding, provides an inert atmosphere for materials.
Our body needs oxygen to obtain energy to fuel all our living processes. Carbon dioxide is a waste product of that process. The respiratory system, with its conduction and respiratory zones, brings air from the environment to the lungs and facilitates gas exchange both in the lungs and within the cells.
Answer:
Air contains some gases, water vapour and dust particles. The gases in air include nitrogen, oxygen, small amount of carbon dioxide and many other gases.
The gases that make up maximum proportion are nitrogen (78%) and oxygen (21%).
Remaining 1% us constituted by carbon dioxide and few other gases, water vapour and dust particles.
