Question

Increase the air pressure of a sealed fish tank to 2 atm from 1 atm by pumping in extra air

What is the partial pressure of oxygen with 1 atm air before the pressure increase (suppose air has 20% oxygen)?

Answer 1

Answer #1

Solution:

The Formula for partial pressure of an individual gas is

Pi =[ ni / ntotal ] * Ptotal ----(i)

Where, ni / ntotal = Mole fraction of Gas..

Before increase pressure , Total Pressure For Oxygen is Ptotal = 1 atom.

The Oxygen partial pressure then equates to -

Pi = [20% / 100%] * 1atm = 0.2 atm

Therefore, Partial Pressure for of Oxygen with 1 atm is 0.2 atm...

A scuba tank is filled with air to a gauge pressure of 204 atm when the air temperature is 33 ∘C. A diver then jumps into the ocean and, after a short time on the ocean surface, checks the tank's gauge pressure and finds that it is only 196 atm. Assuming the diver has inhaled a negligible amount of air from the tank, what is the temperature of the ocean water? Express your answer to two significant figures and include...
