Question

Does concentration of air change with altitude? Yes or no​

Answer 1

Answer:

Air density is higher at lower altitudes. There is more space between air molecules at higher altitudes. There is less oxygen to breathe at the top of a high mountain than there is at sea level.

Answer 2

Yes, the concentration does change.

• The proper stretch upwards from sea level is known as altitude, and it is linked to air pressure.
• Air pressure decreases as altitude increases. To put it another way, if the height displayed is steep, the air pressure is low.
• Gravity is the possible explanation for this. The gravitational attraction of the Earth rends air as close to the surface as feasible.
• Another consideration is density. As altitude rises, quantity of gas molecules in the atmosphere decreases, causing the air low concentrated than at sea size. They have fewer chances to collide when air expands as it rises.
