| Q. |
The velocity of sound in moist air is more than in dry air because the moist air has |
| A. | less density than city air |
| B. | less pressure than dry air |
| C. | more pressure than dry air |
| D. | more density than dry air |
| Answer» A. less density than city air | |
|
Explanation: The density of dry air is more than that of moist air (when moisture is removed from air, its density. increases). The speed of sound in a medium is inversely proportional to the square root of its density. Therefore, the speed of sound in moist air is more than that in dry air. |
