1. Describe Kinetic Molecular Theory.
2. Using the kinetic molecular theory, explain why a gas can be easily compressed, while a liquid and a solid cannot?
3. How do molecular forces affect surface tension?
4.What does the negative slope of water's solid/liquid equilibrium line indicate? Why is
carbon dioxide's positive?

Answer:
1.)Kinetic Molecular Theory states that gas particles are in constant motion and exhibit perfectly elastic collisions. Kinetic Molecular Theory can be used to explain both Charles' and Boyle's Laws. The average kinetic energy of a collection of gas particles is directly proportional to absolute temperature only.
