Do ambient Pressure increase with elevation?

In: Physics [Edit categories]

Answer:

Actually, quite the opposite. The pressure drops as one increases elevation. For example, at 40000 ft, the elevation a plane might fly, the Pambient will be 18.75 kPa, much lower than what is seen at sea level (101 kpa or one atm). At 18 km up, the pressure will be somewhere around 7 kpa, and above this level, it drops dramatically. It is the reason why people who climb Mount Everest need air tanks for oxygen. As the elevation goes up, pressure and temperature go down, and, according to the ideal gas law, less air is present at the summit of Everest. Hope this helps!

Why does pressure increase as elevation increase?
because the clouds create a mist that is full of H, which can touch the earths atmosphere. it creates pressure in our ears because the ear wax chemically reacts to the H
What happens to fliud pressure as elevation increases?
it elevates unless you can control it.

Does air pressure increases with elevation?
No, air pressure decreases with increasing elevation. This is because air pressure is due to the weight of the column of air above where you are. The higher you go, the less air there is above you,...
If pressure increases does the mass increase?
No. Mass is the amount of matter in an object. Pressure does not affect the amount of matter.Uless you have anhydrous ammonia and have a contained vessel at 32psi,that drops to 0 psi suddenly.Then...
