Regarding speed of sound in a gas match the following columns.
(
)
| Column I | Column II | ||
| (A) | (p) | Speed becomes 2 \sqrt{2} times | |
| (B) | (a) | Speed becomes 2 times | |
| (C) | (r) | Speed remains unchanged | |
| (D) | (s) | Speed remains half |
Options
- A((A \rightarrow q, B \rightarrow r, C \rightarrow q, D \rightarrow s))
- B((A \rightarrow r, B \rightarrow s, C \rightarrow q, D \rightarrow p))
- C((A \rightarrow s, B \rightarrow p, C \rightarrow q, D \rightarrow r))
- D((A \rightarrow p, B \rightarrow q, C \rightarrow r, D \rightarrow s))
Correct answer
A. ((A \rightarrow q, B \rightarrow r, C \rightarrow q, D \rightarrow s))
Step-by-step solution
(v=\sqrt{\frac{\gamma R T}{M}}=\sqrt{\frac{v p}{\rho}})
Speed does not change with change in pressure unless temperature is changed.
