What is partial pressure?
the pressure exerted by one of the gases in a mixture if it occupies the same volume on its own
What is the pressure exerted by one of the gases in a mixture if it occupies the same volume of its own
partial pressure
What is related to the number of molecules in the system?
partial pressure
What is partial pressure related to?
the number of molecules in the system
more particles =
higher partial pressure
Higher partial pressure =
more particles
What does Dalton’s Law state?
In a mixture of gases, the total pressure is the sum of the partial pressures of the component gases
