A very large container consists of an ideal gas. The speed of sound in the gas is x. When the pressure of the gas is doubled while keeping the temperature constant, the speed of sound now becomes y. What is the ratio of x to y?
- A. 1 ✓
- B. \sqrt{2}
- C. 2
- D. 4
Correct Answer: A. 1
Explanation
The speed of sound in an ideal gas depends only on its temperature and is independent of its pressure. Thus, the speed remains the same and the ratio is 1.
