NEET Physics Ideal Gas Equation MCQ Question
Which of the following statements about the ideal gas equation and partial pressures is correct?
The total pressure of a gas mixture is equal to the sum of individual gas pressures when each gas behaves ideally.
The partial pressure of a gas in a mixture is always equal to its molar mass divided by the total pressure.
Dalton’s law states that the partial pressure of each gas in a mixture is independent of the volume and temperature of the mixture.
The ideal gas equation applies only to gases that do not exhibit any intermolecular forces.
Correct Answer
Detailed Explanation
According to the NCERT context, the total pressure of a mixture of ideal gases is indeed the sum of the partial pressures of its constituent gases, consistent with Dalton’s law of partial pressures.
