16
Category 2 600

• A closed 1 L system contains H2 gas. How will an
  increase in temperature effect the pressure in
  the container.

17
Category 2 800

• Compare the entropy of H2O(g) to H2O(s)

18
Category 2 1000

• Describe an ideal gas according to the Kinetic
  Molecular Theory.
• Your answer must include 4 pieces of information.

19
Category 2 200-Answer

• Decrease temperature, increase pressure

20

  are more disordered.

23
Category 2 1000-Answer

1. Particles have random motion
2. No attraction between particles.
3. Particles are small compared to the space between
   them.
