Amagat's Law Formula |

| \( V_{mixture} \;=\; V_1 + V_2 + V_3\; +...V_n \) | ||
| Symbol | English | Metric |
| \( V_{mixture} \) = the volume of a mixture | \( ft^3 \) | \( m^3 \) |
| \(V_1 V_2 V_3 ...V_n \) = the partial volume of its components | \(\ ft^3 \) | \( m^3 \) |
Amagat's law, also called the law of partial volumes, states that the volume of a mixture is equal to the sum of the partial volume of its components. It assumes that the gases in the mixture do not interact with each other and behave as ideal gases. Both Amagat's law and Dalton's law predict the properties of gas mixtures. The law is only valid for ideal gases.
Amagat's law is particularly useful when dealing with gas mixtures at high pressures, where the individual gases behave as ideal gases and do not significantly interact with each other. It allows for the determination of the total volume of the mixture based on the volumes of the individual components. However, it is important to note that Amagat's law is an approximation and assumes ideal gas behavior. In reality, gas interactions, such as deviations from ideal behavior and molecular interactions, can occur, especially at high pressures or when dealing with non-ideal gases. In such cases, more accurate equations of state or models may need to be employed to describe the behavior of the gas mixture.
