In summer season, with the rise of temperature, the velocity of sound
Correct answer: A. increases
- A. increases
- B. decreases
- C. becomes zero
- D. remains constant
Explanation
A) increases * Sound travels by vibrating molecules. When the temperature of a medium (like air) increases, the molecules gain more kinetic energy and vibrate faster. This increased molecular motion allows sound waves to transfer energy more efficiently and thus travel at a higher speed. * The speed of sound in a gas is directly proportional to the square root of its absolute temperature (in Kelvin). This means as temperature rises, the speed of sound also rises.

About Speed of Sound
The speed of sound depends on the properties of the medium, including its elasticity and density, and in gases it varies mainly with temperature. Questions connect speed with frequency and wavelength, compare sound in solids, liquids and gases, and distinguish the speed of propagation from the oscillating particles' motion.
