| 2. | The speed of sound in oxygen (O2) at a certain temperature is 460m/s. The speed of sound in helium (He) at the same temperature will be (assume both gases to be ideal). | |
| A. | 460m/s | |
| B. | 500m/s | |
| C. | 650m/s | |
| D. | 1420m/s | |
| Answer: Option D | |
| Explanation: | |
|
vHe/v(O2) = √(γHe/γ(O2) ×M(O2)/MHe)=√((5/3)/(7/5)×32/4)=√(200/21) |
