Think of a pool-table set up as a model (analogy) for gas behavior:
a. How would you use the pool balls to demonstate the effect of an increase in the temperature of a gas sample?
b. How would you use this model to demonstrate the effect of adding more gas molecules to the sample?
c. In what ways is the pool-table model unsuccessful and misleading in modeling gas behavior?
