| Q. |
Which set of conditions represents the easiest way to liquiify a gas? |
| A. | Low temperature and high pressure |
| B. | High temperature and low pressure |
| C. | Low temperat.ure and low pressure |
| D. | High temperature and high pressure |
| Answer» A. Low temperature and high pressure | |
|
Explanation: Low temperature and high pressure set of conditions represents the easiest way to liquefy a gas. Liquefaction of gases is physical conversion of a gas into a liquid state (condensation). The processes are used for scientific, industrial and commercial purposes. Many gases can be put into a liquid state at normal atmospheric pressure by simple cooling; a few, such as carbon dioxide, require pressurization as well. |
