An ideal gas is allowed to expand adiabatically until its volume increases by 50. By approximately what factor is the pressure reduced? (g = 5/3.)
 a. 1.5
  b. 2.0
  c. 2.5
  d. 3.0
  e. 3.5

Question 2

During an adiabatic compression, a volume of air decreases to 1/4 its original size. Calculate its final pressure if its original pressure was 1 atm. (Assume the air behaves like an ideal gas with g = 1.4.)
 a. 7.0 atm
  b. 5.6 atm
  c. 3.5 atm
  d. 2.2 atm
  e. 0.14 atm
