All living things have evolved under this very heavy mass of air, and as a result, they have all evolved to exert an equal and opposite pressure internally. It requires no effort and no one feels this, of course; the body does this quite naturally.
The stratosphere is right above the troposphere, which is what we live in. The ozone layer exists within the stratosphere. It extends up to about 50km above the surface.
No, air can exist in different states depending on the temperature and pressure. At standard atmospheric conditions, air exists as a gas, but it can condense into a liquid or freeze into a solid at lower temperatures.
Water vapor is the atmospheric gas that exists in variable amounts. Its concentration can vary depending on factors such as temperature and location.
I believe that you mean to ask why the atmospheric pressure of 24 pounds per square inch does not crush living organisms. That pressure exists both inside and outside of living organisms; air is inside us as well as outside, since we inhale it. And the parts that have no air are permeated by water, which is relatively incompressible. An organism would only feel the air pressure as a crushing force if it had a section of its body which contained a vacuum, and there is no living organism which does.
The temperature increases with altitude in the troposphere because of the absorption of solar radiation by the Earth's surface, which heats up the air closer to the surface. As you move higher in the troposphere, the air becomes thinner and less able to retain this heat, causing a decrease in temperature.
Atmospheric pressure exists because air has weight. The weight of the air above exerts a force on the air below it, resulting in pressure at the Earth's surface.
The stratosphere is right above the troposphere, which is what we live in. The ozone layer exists within the stratosphere. It extends up to about 50km above the surface.
This pressure, of nearly one atm., is basically the atmospheric pressure which exists at sea level.
It wasn't "invented". It exists whenever the planet's atmosphere forms.
At the atmospheric pressure, liquid nitrogen only exists in temperatures below 177 K.
Atmospheric pressure, energy level, polymorphs, isotopes, and alot of other factors.

The concept of air pressure was first discovered by Evangelista Torricelli, an Italian physicist and mathematician, in 1643. He invented the mercury barometer to measure atmospheric pressure, which led to the understanding of how air pressure behaves in different conditions.
Water vapor is the atmospheric gas that exists in variable amounts. Its concentration can vary depending on factors such as temperature and location.
Nitrogen exists as a gas at room temperature and atmospheric pressure. It is a colorless, odorless, and tasteless diatomic gas with the chemical formula N2.
The layer of the atmosphere closest to Earth where all life exists and weather takes place is the troposphere. It extends from the Earth's surface to an average height of about 8 to 15 kilometers.
