9.9 – Combined Gas Law notes
-The Combined Gas Law is a combination of the previous 3 gas laws we have learned about.
This is the law you use if neither pressure, temperature, or volume is ____________________ for a
given problem.
What mathematical equation defines the Combined Gas Law? Identify all variables.
Example 1: The volume of a gas is 27.5 mL at 22 0C that has a pressure of 0.974 atm. What will
the new volume of the gas be if the temperature drops to 15 0C and the pressure increased to
0.993 atm?
