partial pressure
Single gas's contribution
Partial pressure is the pressure that one gas in a mixture would exert if it alone occupied the entire volume.
In a container holding oxygen and nitrogen, each gas contributes its partial pressure to the total.
The concept is essential in chemistry, diving, and respiratory physiology: The partial pressure of oxygen decreases at high altitudes.
