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

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
