Laplace corrected Newton's formula for the velocity of sound in gas because the sound propagates:
Correct answer: B. Adiabatically
- A. As longitudinal
- B. Adiabatically
- C. Isothermally
- D. Under isobaric conditions
Explanation
The transfer of energy is in the form of work done, during sound propagation so it is an adiabatic process

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.
