The air in an automobile engine at 20C is compressed from an initial pressure of 1.0 atm and a volume of 200 cm3 to a volume of 20 cm3 . Find the temperature if the air behaves like an ideal gas (g = 1.4) and the compression is adiabatic.
 a. 730C
  b. 460C
  c. 25C
  d. 50C
  e. 20C

Question 2

 a. No work is done on or by the gas when the volume remains constant.
  b. No energy is transferred into or out of the gas as heat transfer when the temperature remains constant.
  c. The internal energy of the gas does not change when the pressure remains constant.
  d. All the statements above are correct.
  e. Only statements (a) and (b) above are correct.
