Which of the following names corresponds with the law that states the total pressure of a combined mixture of gases is the sum of the pressures of each constituent gas?

• A. Charles's Law
• B. Boyle's Law
• C. Avogadro's Law
• D. Dalton's Law

Answer: (D)

The law that states the total pressure of a combined mixture of gases is the sum of the pressures of each constituent gas is known as Dalton's Law. This principle, formulated by John Dalton, describes how in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of each individual gas in the mixture. This law is fundamental in understanding how gases behave in a variety of applications, including engineering and atmospheric science. For instance, when analyzing a gas mixture, you can calculate the total pressure by measuring the individual pressures exerted by each gas, demonstrating the additive nature of gas pressures as long as the temperatures and volumes remain constant. This relationship is critical for the operation of systems involving gas mixtures, such as in combustion engines or HVAC systems where understanding the behavior of air and fuel mixtures is vital for efficiency and safety. The other mentioned laws focus on different gas properties: Charles's Law deals with the relationship between volume and temperature, Boyle's Law relates pressure and volume at constant temperature, and Avogadro's Law pertains to the volume of gas and the number of moles at a constant temperature and pressure. Each of these laws highlights different aspects of gas behavior, making them important in their own contexts,
