What is the velocity of sound at 100 oC if the velocity of sound at 0 oC is 340ms -1?
-
A.
497m-1 -
B.
440m-1 -
C.
397m-1 -
D.
240m-1
Correct Answer: Option 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})
