1) We state that the ideal gas law tends to hold best at low pressures and high tempuratures.Show how the Van der Waal's equation simplifies to the ideal gas law under these conditions.

2) Consider separate 1.00 L samples of Ar (g), both containing the same number of moles, on at 27 degrees C and the other at 77 degrees C. Compare the change in momentum per impact and the number of impacts per second in the 2 samples.
