Hence, what ever <a href="https://interviewquestions.tuteehub.com/tag/amount-374803" style="font-weight:bold;" target="_blank" title="Click to know more about AMOUNT">AMOUNT</a> of heat is generated at agiven <a href="https://interviewquestions.tuteehub.com/tag/postion-2944657" style="font-weight:bold;" target="_blank" title="Click to know more about POSTION">POSTION</a> in air medium, same amount of heat is absorbed there only when rarefaction takes place at the same position after half <a href="https://interviewquestions.tuteehub.com/tag/period-1151023" style="font-weight:bold;" target="_blank" title="Click to know more about PERIOD">PERIOD</a> `T/2.` Thus, there is no transfer of heat and hence this process can be taken as adiabatic.</body></html>
