Answer: ______
14.Complete the following table:
Increase on this variable leads to….. / With this variable held constant / This variable increases, decreases, or no change….. / Why?Pressure / Temperature / Volume…decreases / Boyles Law is an inverse relationship, so if one variable increases, the other must decrease.
Pressure / Volume / Temperature
Volume / Pressure / Temperature
Temperature / Pressure / Volume
Temperature / Volume / Pressure
Volume / Temperature / Pressure
Moles / volume
Moles / Pressure
15.State at least two differences between “ideal” and “real” gases that are in accordance with the kinetic theory.
