An ideal gas at pressure, volume, and temperature, P0, V0, and T0, respectively, is heated to point A, allowed to expand to point B also at As temperature 2T0, and then returned to the original condition. The internal energy increases by 3P0V0/2 going from point T0 to point A. How much heat entered the gas from point T0 to point A?
 
   
   
  a.
  0
  b.
  P0V0/2
   
  c.
  3P0V0/2
  d.
  5P0V0/2

Question 2

As the ideal gas expands from pressure P1 and volume V1 to pressure P2 and volume V2 along the indicated straight line, it is possible that:
 
   
   
  a.
  the temperature stays constant.
   
  b.
  the internal energy decreases.
   
  c.
  the gas is changing state.
   
  d.
  all of the above are impossible for this particular graph.
