Topic: Fluid Mechanics
The velocity of sound in winter compared to summer will be
- A. higher
- B. lower
- C. same
- D. cannot be predicted
Answer: B. lower
Explanation: The velocity of sound in a gas is given by the formula $C = \sqrt{\gamma R T}$, making it directly proportional to the square root of the absolute temperature ($T$). Since the ambient temperature is naturally lower in the winter compared to summer, the velocity of sound decreases correspondingly.
