Dalton's Law of Partial Pressures:
Dalton's Law of Partial Pressures states that the total pressure of a mixture of gases is equal to the sum of the pressures that each gas would exert if it were present alone and occupied the same volume.
This law is also known as Dalton's Law of Additivity of Pressures.
The law can be expressed mathematically as:
Ptotal = P1 + P2 + P3 + ......
where Ptotal is the total pressure of the gas mixture, and P1, P2, P3, ... are the partial pressures of each gas in the mixture.
In other words, the partial pressure of a gas in a mixture is equal to the pressure that the gas would exert if it were alone in the container at the same temperature and volume as the mixture.
- Dalton's Law is useful in several applications, including the determination of the composition of a gas mixture and the prediction of the behavior of gases under different conditions.
- It is a fundamental concept in the field of thermodynamics and is widely used in the study of atmospheric chemistry, combustion, and the design of gas storage and delivery systems.
