ANS:B - Amgat's

The statement "The total volume occupied by a gaseous mixture is equal to the sum of the pure component volumes" corresponds to Amagat's Law. This law states that the volume occupied by a mixture of gases at constant temperature and pressure is equal to the sum of the volumes that each gas would occupy if it alone occupied the entire volume under the same conditions. Amagat's Law is a fundamental principle in the study of gas mixtures, named after the French physicist Émile Amagat. It states that "the total volume occupied by a mixture of gases at a given temperature and pressure is equal to the sum of the volumes that each gas would occupy if it alone occupied the entire volume under the same conditions." Mathematically, Amagat's Law can be expressed as: 𝑉total=𝑉1+𝑉2+𝑉3+…Vtotal​=V1​+V2​+V3​+… Where:

• 𝑉totalVtotal​ is the total volume of the gas mixture,
• 𝑉1,𝑉2,𝑉3,…V1​,V2​,V3​,… are the volumes of the individual gases in the mixture.

This law holds true for ideal and real gases under conditions where there are no chemical reactions or significant interactions between the gas molecules. It essentially states that the volume of a gas mixture is the sum of the volumes of its individual components. Amagat's Law is particularly useful in various fields, including chemistry, physics, and engineering, where the behavior of gas mixtures needs to be understood and analyzed. It helps in predicting the behavior of gas mixtures under different conditions and in various processes, such as in industrial applications, combustion processes, and gas storage systems.
