Question

What do you mean by atmospheric pressure? And why do mountaineers carry gas tanks with them?

Answer 1

Answer:

the pressure exerted by the weight of the atmosphere, which at sea level has a mean value of 101,325 pascals (roughly 14.6959 pounds per square inch).

Mountaineers carry oxygen cylinder while climbing high mountains to avoid suffocation. As we go higher and higher, at high altitudes, amount of oxygen present in the atmosphere is determined by atmospheric pressure. ... This decreases the number of oxygen molecules per breath making the person suffocated at high altitudes.

Hope that this helps

Answer 2

Answer:

The pressure exerted by the weight of the atmosphere, which at sea level has a mean value of 101,325 pascals (roughly 14.6959 pond per square inch)

Mountaineers carry gas tank with them because at the higher altitude oxygen became less so mountaineers carry gas tank with them.

I hope helpfull to you
