1.	Troposphere is extended up to 6-20 km altitude from the earth's surface but the amount of oxygen is less at higher altitudes, that is on mountains or hill tops. Justify.
Answer» Solution :The vapour densityy of OXYGEN is 16 and that of the air is 14.4. Hence due to higher vapour density of oxygen its amount in air DECREASE on higher altitudes such as mountains that is more denser MOLECULES experience more gravitational PULL.
