Given below are two statements:
| Assertion (A): | Gases do not liquefy above their critical temperature, even on applying high pressure. |
| Reason (R): | Above the critical temperature, the molecular speed is high and intermolecular attractions cannot hold the molecules together because they escape because of high speed. |
