The propagation of sound waves in a gas involves
A. Adiabatic compression and rarefaction
B. Isothermal compression and rarefaction
C. Isochoric compression and rarefaction
D. Isobaric compression and rarefaction
Answer: Option A
Solution (By Examveda Team)
An adiabatic process is one that occurs without transfer of heat or matter between a thermodynamic system and its surroundings. In an adiabatic process, energy is transferred only as work.Rarefaction is the reduction of an item’s density, the opposite of compression.
