Boyle's Law Answers

1.  The volume of the lungs is measured by the volume of air inhaled or exhaled.  If the
     volume of the lungs is 2.400 L during exhalation and the pressure is 101.70 KPa, and the
     pressure during inhalation is 101.01 KPa, what is the volume of the lungs during inhalation? 

     2.412L
              

2.  The total volume of a soda can is 415 mL.  Of this 415 mL, there is 60.0 mL of headspace
      for the CO₂ gas put in to carbonate the beverage.  If a volume of 100.0 mL of gas at
      standard pressure is added to the can, what is the pressure in the can when it has been
      sealed?

     169 KPa
       

3.  It is hard to begin inflating a balloon.  A pressure of 800.0 Kpa is required to initially inflate
     the balloon 225.0 mL.  What is the final pressure when the balloon has reached it's capacity
     of 1.2 L?

     150 KPa
       

4.  If a piston compresses the air in the cylinder to 1/8 it's total volume and the volume is 930
     cm³  at STP, what is the pressure after the gas is compressed? 

     810 KPa
       

5.  If a scuba tank that has a capacity of 10.0 dm³  is filled with air to 500.0 KPa, what will be
     the volume of the air at 702.6 KPa? 

     7.11 dm³
