What is the sum of the pressures for each gas in a confined mixture known as?

The sum of the pressures for each gas in a confined mixture is known as Dalton's Law. This law states that in a mixture of non-reacting gases, the total pressure exerted by the mixture is equal to the sum of the partial pressures of each individual gas present in the mixture. Each gas in the mixture behaves independently and contributes to the overall pressure, which is a fundamental principle in understanding gas behavior.

Dalton's Law is pivotal in various applications, including calculations in chemistry and engineering involving gas mixtures. In practical terms, this allows for the assessment of how different gases within a confined space exert pressures and how those pressures combine to give the total pressure of the gas mixture. This understanding is essential for tasks such as determining the concentration of gases in refrigeration and air conditioning systems.

The other laws mentioned, such as Boyle's Law, Charles' Law, and Pascal's Law, govern different aspects of gas behavior and pressure. Boyle's Law relates pressure and volume for a gas at constant temperature, Charles' Law focuses on the relationship between volume and temperature, and Pascal's Law addresses the transmission of pressure in fluids. Each of these laws applies to specific circumstances but does not describe the total pressure in a mixture of gases as Dalton's Law does.
