44. 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
Option A Solution: 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.
