Volume of 2.93 L, what will its pressure? 0.499 am 3. Hospitals buy 400-L cylinders of oxygen gas compressed at 150 atm. They administer oxygen to
patients at 3.0 atm in a hyperbaric oxygen chamber. What volume of oxygen can a cylinder
supply at this pressure?
?

The volume of Oxygen : 20,000 L

Given

400 L : initial volume

150 atm  : initial pressure

3 atm : final pressure

Required

Final volume

Solution

Boyle's Law  

At a fixed temperature, the gas volume is inversely proportional to the pressure applied  

Input the value :

V₂ = (P₁V₁)/P₂

V₂ = 150 atm x 400 L / 3 atm

V₂ = 20,000 L

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
