| Statement I: | On reducing the volume of a gas at a constant temperature, the pressure of the gas increases. |
| Statement II: | At constant temperature, according to Boyle’s law, volume is inversely proportional to the pressure. |
| 1. | Statement I is correct and Statement II is incorrect. |
| 2. | Statement I is incorrect and Statement II is correct. |
| 3. | Both Statement I and Statement II are correct. |
| 4. | Both Statement I and Statement II are incorrect. |

A given sample of an ideal gas occupies a volume \(V\) at a pressure \(P\) and absolute temperature \(T\). The mass of each molecule of the gas is \(m\). Which of the following gives the density of the gas?
| 1. | \(\dfrac{P}{kT}\) | 2. | \(\dfrac{Pm}{kT}\) |
| 3. | \(\dfrac{P}{kTV}\) | 4. | \(mkT\) |

| 1. | \(1\) | 2. | \(\dfrac32\) |
| 3. | \(\dfrac23\) | 4. | \(\dfrac54\) |
| 1. | \(PV = 8RT\) | 2. | \({PV}{=}\dfrac{RT}{4}\) |
| 3. | \(PV = RT\) | 4. | \({PV}{=}\dfrac{RT}{2}\) |
Two vessels separately contain two ideal gases A and B at the same temperature, the pressure of A being twice that of B. Under such conditions, the density of A is found to be 1.5 times the density of B. The ratio of molecular weight of A and B is:
1. 2/3
2. 3/4
3. 2
4. 1/2
