Q. No.Given below are two statements:
| Assertion (A): | As a gas bubble rises from the bottom of a lake, its volume decreases. |
| Reason (R): | As the gas bubble rises from the bottom of a lake, the pressure of the gas within decreases. |
| 1. | (A) is True but (R) is False. |
| 2. | (A) is False but (R) is True. |
| 3. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 4. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |

The figure shows a plot of \(\frac{PV}{T}\) versus \(P\) for \(1.00 \times 10^{- 3}~\text{kg}\) of oxygen gas at two different temperatures.
The value of \(\frac{PV}{T}\) where the curves meet on the \(y\text-\)axis is:
1. \(0.06~\text{JK}^{-1}\)
2. \(0.36~\text{JK}^{-1}\)
3. \(0.16~\text{JK}^{-1}\)
4. \(0.26~\text{JK}^{-1}\)

Given below are two statements:
| Assertion (A): | A gas can be liquified at any temperature by an increase of pressure alone. |
| Reason (R): | On increasing pressure, the temperature of gas decreases. |
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
| 3. | (A) is true but (R) is false. |
| 4. | Both (A) and (R) are false. |
