A sample of gas has its number of molecules halved, its Kelvin temperature doubled, and its volume halved. What is the new pressure, relative to the original pressure?

Question 2

Which of the effects listed below is not a major effect influencing the binding energy of the nucleus in the liquid-drop model?
 a. The volume effect: the binding energy per nucleon is approximately constant when A > 50.
  b. The surface effect: nucleons in the surface have fewer neighbors.
  c. The quantum number effect: all nucleons in the nucleus have the same set of quantum numbers.
  d. The Coulomb repulsion effect: protons repel protons.
  e. The symmetry effect: stable nuclei tend to have N  Z.
