A fixed amount of ideal gas is held in a rigid container that expands negligibly when heated. At 20C the gas pressure is p. If we add enough heat to increase the temperature from 20C to 40C, the pressure will be
 
  A) impossible to determine since we do not know the number of moles of gas in the container.
  B) greater than 2p.
  C) less than 2p.
  D) equal to 2p.
  E) impossible to determine since we do not know the volume of gas in the container.

Question 2
