Air at sea level is dense. This is practical application of?

Correct Answer: D. Daltons Law

Dalton’s Law of Partial Pressures states that in a mixture of gases, the total pressure is the sum of the partial pressures of individual gases. At sea level, the atmosphere is composed of various gases, with nitrogen and oxygen being the primary components. The density of the atmosphere, which is related to the pressure, is a practical application of Dalton’s Law. The total atmospheric pressure is the result of the partial pressures of these gases, making the air denser at sea level compared to higher altitudes.
