What is the velocity of sound at 100 oC if the velocity of sound at 0 oC is 340ms -1?
- 497m-1
- 440m-1
-
397m-1
- 240m-1
The correct answer is: C
Explanation
\(V \propto \sqrt{T}\)
⇒ \(\frac{V_{1}}{\sqrt{T_{1}}} = \frac{V_{2}}{\sqrt{T_{2}}}\)
Using the above formula, we get
\(V_{2} \approxeq 397ms^{-1}\)
