A sound wave is passing through air column in the form of compression and rarefaction. In consecutive compressions and rarefactions.

A

(a)denisty remains constant.

B

(b) Boyle's law is obeyed.

C

(c) bulk modulus of air oscillates.

D

(d) there is no transfer of heat.

Text Solution

Verified by Experts

The correct Answer is:
D
During the propagation of sound in air, condensations take place at a given positon, rapidly and periodically. Hence, what ever amount of heat is generated at a given postion in air medium, same amount of heat is absorbed there only when rarefaction takes place at the same position after half period `T/2.` Thus, there is no transfer of heat and hence this process can be taken as adiabatic.

The arms of a U shaped tube are vertical. The arm on right side is closed and other arm is closed by light movable piston. There is mercury in the tube and initially the level of the mercury in the arms is the same. Above the mercury, there is an air column of height h in each arm, and initial pressure is the same as atmospheric pressure in both arms. Now pistion is slowly pushed down by a distance of h//2 (see figure) Let x is the displacement of mercury level in one of the stem and P_(1) is pressure in left column of air after compression, P_(2) is pressure in right column of air after compression and P_(0) is atmospheric pressure then
