Given below are two statements:
| Assertion (A): | Three states of matter are the result of a balance between intermolecular forces and the thermal energy of the molecules. |
| Reason (R): | Intermolecular forces tend to keep the molecules together but the thermal energy of molecules tends to keep them apart. |
| 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. | (A) is false but (R) is true. |
Given below are two statements:
| Assertion (A): | At constant temperature, pV vs p plot for real gases is not a straight line. |
| Reason (R): | At high pressure, all gases have Z>1 but at an intermediate pressure most gases have Z<1. |
| 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. | (A) is false but (R) is true. |
