When animals inhale air, oxygen will move into the lungs due to the difference in partial pressure of oxygen in the lungs and atmosphere. This obeys
Correct answer: B. Dalton's law
- A. Pascal's law
- B. Dalton's law
- C. Charles's law
- D. Bohr's law
Explanation
When animals inhale air, oxygen will move into the lungs due to the difference in partial pressure of oxygen in the lungs and atmosphere. This obeys DALTON'S LAW. Dalton's law (also called Dalton's law of partial pressures) states that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases.

About Ideal Gas Equation
The ideal gas equation, PV = nRT, relates pressure, volume, amount and absolute temperature when gas particles are assumed to have negligible volume and no intermolecular forces. Applications include finding molar mass, density or an unknown gas variable, with careful use of Kelvin temperature and consistent units, and comparison with real-gas behaviour.
