Why does a person feel difficult to breathe when he is in a deep well?

Please answer!!!

Carbondioxide is heavier than air. In the well, carbondioxide displaces the air present inside the well and only carbondioxide gas is collected at the bottom. So, there is lack of oxygen. Hence the person feels difficult to breathe while cleaning the deep well.

The person feels difficult to breathe in a deep well while cleaning it because the density of oxygen is less than the density of the carbon dioxide that eventually makes the presence of oxygen less in the well. So, the person don't get the required amount of oxygen and the person feels it difficult.

If you stay there long enough to decrease the oxygen and increase the CO2 and there is no input of fresh air that could happen.

a deep well allows for little air circulation and the components of the atmosphere can stratify to a certain extent

oxygen (which we need to breathe) is not the densest component
the noble (inert) gas, argon, makes up about 1% of air; and is the heaviest

as already mentioned, carbon dioxide is heavier than oxygen; and is produced by the person

the decreasing amount of oxygen in the air presents a real danger of suffocation

it is the lowered PARTIAL PRESSURE of oxygen, coupled with the increased PP of carbon dioxide that causes problems

It is because there is presence of other gases like co2 rather than o2. So due to less availability of o2 in deep well and presence of more density of other gases one feel difficult to breathe. Thank you

Then why in earth surface all gases are mixed , there also should be carbon dioxide in the surface?

When a person is in a deep well, they may feel it difficult to breathe due to multiple factors. One possible reason is the lack of oxygen in the confined space of the well, especially if it is poorly ventilated or has limited air circulation. Another reason could be related to the psychological effect known as claustrophobia, which is the fear of confined spaces. Being enclosed in a deep well can trigger feelings of anxiety and panic, potentially leading to difficulty in breathing.

However, it's important to note that the specific circumstances and conditions of the well can vary greatly. If you or someone you know is experiencing difficulties breathing in a deep well, it is crucial to prioritize safety and seek immediate help from trained professionals, such as emergency responders or rescue teams.

In general, enclosed spaces with limited airflow and low oxygen levels pose significant risks to human health. It is always best to avoid or take proper precautions when entering areas with these characteristics.

I do not have a lot of trouble breathing with SCUBA gear under 100 feet of water. The pressure there is far greater than that in any deep well full of air that I can imagine. Perhaps this well is full of water?

I suppose the increased pressure by increased density of gas makes it harder to inhale and exhale, but I have never noticed that. I think the question is pretty phony and whoever wrote it is not a diver.

is there presence of co2 so the density of air is increased?????
