Vedclass · Answer

(A) Laplace corrected Newton's formula for the speed of sound by assuming that the propagation of sound in air is an adiabatic process.In an adiabatic process,there is no exchange of heat between the system and the surroundings.This assumption is justified because air is a poor conductor of heat and the compressions and rarefactions occur so rapidly (due to the high velocity of sound) that there is insufficient time for any significant heat exchange to take place between the regions.Therefore,both the Assertion and the Reason are correct,and the Reason provides the correct explanation for the Assertion.

$Assertion :$ The base of Laplace correction was that exchange of heat between the region of compression and rarefaction in air is negligible.
$Reason :$ Air is a bad conductor of heat and the velocity of sound in air is quite large.
