Explains Dalton's law using animations to demonstrate the concept.
Focuses on a container with three different gases: Gas 1, Gas 2, and Gas 3.
All gases are in the same container, meaning they have the same volume.
Key Points
Concept Explanation
Same Volume: In the container, all gases share the same volume.
Partial Pressures: When gases are distributed equally, the sum of the partial pressures of the individual gases equals the total pressure of the gas mixture.
Pressure Meters: By observing pressure meters above gas chambers, one can see that each partial pressure of individual gases adds up to the total pressure in the container.
Formula Derivation
Ideal Gas Law: (PV = nRT)
Derived as Pressure ((P)) = (\frac{nRT}{V})
Dalton's Law of Partial Pressure: At a constant volume, the sum of the partial pressures of individual gases equals the total pressure of the combined gases.
Example Problem
Given:
Gas mixture contains Hydrogen, Helium, Neon, and Argon.
Total Pressure: 93.6 kPa
Partial Pressures:
Helium: 15.4 kPa
Neon: 24.7 kPa
Argon: 35.6 kPa
Find: Pressure exerted by Hydrogen.
Solution:
Calculate total partial pressures of Helium, Neon, and Argon.
Subtract from total pressure to find Hydrogen's pressure.
Hydrogen's Pressure: 16.9 kPa
Conclusion
The example question illustrates the application of Dalton's law of partial pressures effectively.
