NEET Physics Ideal Gas Equation Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Total Pressure | (i) Sum of partial pressures |
| (b) Partial Pressure | (ii) Pressure exerted by one gas alone |
| (c) Ideal Gas Law | (iii) P V = nRT |
| (d) Number Density | (iv) Number of molecules per unit volume |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iii, b-iv, c-ii, d-i
a-iv, b-iii, c-i, d-ii
Correct Answer
Detailed Explanation
The total pressure of a mixture of gases is indeed the sum of the partial pressures of the individual gases, as stated in Dalton’s law of partial pressures. Partial pressure refers to the pressure exerted by one gas when occupying the same volume and temperature alone. The ideal gas law is represented by the equation PV = nRT, and number density is defined as the number of molecules per unit volume.
