A container with a one-liter capacity at 27 C is filled with helium to a pressure of 2.0 atm. (1 atm = 1.0  105 N/m2.) How many moles of helium does it hold?
 a. 0.041
  b. 0.081
  c. 0.45
  d. 0.90
  e. 1.0

Question 2

Two identical containers, A and B, hold equal amounts of the same ideal gas at the same Po, Vo and To. The pressure of A then decreases by a half while its volume doubles; the pressure of B doubles while its volume decreases by a half. Which statement correctly describes the temperatures of the gases after the changes?
 a. TA = 0.5TB = To.
  b. TB = 0.5TA = To.
  c. TB = TA = To.
  d. TA = 2TB = To.
  e. TB = 2TA = To.
