Question

Propagation of a sound wave in a gas is quite close to

• A. an adiabatic process
• B. an isothermal process
• C. a process that does not exhibit properties close to any of the three given in $\left(a\right),\left(b\right),\left(c\right)$
• D. an isobaric process

Answer 1

The correct option is A an adiabatic process

Sound wave propagates so fast in a gas that there is no time for the exchange of energy with the medium (gas). Hence, it is similar to adiabatic process.

Final answer : (b)
