Gas Pressure

Key Questions

• How does gas pressure change with volume?

  Answer:

  Well, what does old #"Boyle's Law"# say...

  Explanation:

  #Pprop1/V#...pressure is INVERSELY proportional to volume.

  And so #PV=underbrace(k)_"some constant"#...and under different conditions...with TEMPERATURE constant...

  #P_1V_1=P_2V_2#...
