The proportion of nitrogen in air remains constant because nitrogen is a chemically stable and non-reactive gas. It does not participate in chemical reactions in the atmosphere, so its concentration remains consistent over time. Additionally, the balance of nitrogen in the atmosphere is maintained by processes such as nitrogen-fixing bacteria in the soil and lightning, which help replenish nitrogen levels.

Why the percent amount of Nitrogen in Air remain constant?
The percent amount of nitrogen in the air remains constant because nitrogen gas is a non-reactive gas and does not easily participate in chemical reactions that would alter its composition in the atmosphere. This stability allows the nitrogen component to remain consistently at around 78% of the Earth's atmosphere.
Why is the percentage of nitrogen the same as when you inhale air and exhale air?
The percentage of nitrogen in the air remains constant when you inhale and exhale because the body does not use nitrogen during respiration. While we inhale oxygen and exhale carbon dioxide, the nitrogen in the air is not chemically altered or metabolized by the body's processes.
Why air dissolved in water contains higher proportion of oxygen?
Air contains about 21% oxygen and 78% nitrogen, while water can only dissolve a limited amount of gas. Therefore, the oxygen in air dissolves in water at a higher proportion than nitrogen. This is due to the partial pressure of oxygen being higher in air compared to nitrogen.
What is Percent nitrogen?
Percent nitrogen is a measurement used to indicate the nitrogen content in a substance, such as fertilizer or soil. It represents the proportion of nitrogen by weight in the total weight of the substance. This measurement is important in agriculture and chemistry for understanding nutrient levels and chemical compositions.
What is the percent if the air is nitrogen?
Air is approximately 78% nitrogen.
Why the percent amount of Nitrogen in Air remain constant?

This stability allows the nitrogen component to remain consistently at around 78% of the Earth's atmosphere.
When a sealed bag is compressed does the air pressure decresssed?
Assume temperature remains constant, then the pressure will rise in proportion to the decrease in volume, and vice versa.
What constituents of atmospheric air remains constant a -nitrogen b -water vapour c- smoke particles d -none of the above?
c

What proportion of the air is made up of carbon dioxide oxygen and nitrogen?
nitrogen is 78% while CO2 is part of a percent

When atmospheric pressure on a pond remains constant during hot weather what happens to the force of air on the surface of the pond?
When atmospheric pressure on a pond remains constant during hot weather, the force of air on the surface of the pond also remains constant. Atmospheric pressure is not affected by temperature changes alone, so the force exerted by the air on the pond's surface stays the same.
When air resistance balances the weight of an object that is falling the velocity remains blank?
Constant
What happens to light when it travels from air into denser?
its frequency remains constant but velocity changes.
What danger we have to face if the proportion of oxygen and nitrogen in the air undergo a change?
Difficult respiration if the oxygen is under 20 % followed by death.
As air becomes warmer it becomes less?
As air becomes warmer it becomes less dense (as long as the pressure remains constant)
