An ideal gas in a balloon is kept in thermal equilibrium with its constant-temperature surroundings. How much work is done by the gas if the outside pressure is slowly reduced,
 
  allowing the balloon to expand to 6.0 times its original size? The balloon initially has a pressure of 645.0 Pa and a volume of 0.10 m3. The ideal gas constant is R = 8.314 J/mol  K.
  A) 120 J
  B) 390 J
  C) -330 J
  D) 6.0 J

Question 2

How much work is done by 3.00 mol of ideal gas when it triples its volume at a constant temperature of 127C? The ideal gas constant is R = 8.314 J/mol  K.
 
  A) 12.7 kJ
  B) 9.97 kJ
  C) 11.0 kJ
  D) 15.3 kJ
  E) 1.20 kJ
