In an adiabatic process where in pressure is increased by 23% if CpCv=32, then the volume decreases by about.

a
49%
b
23%
c
4%
d
94%

detailed solution

Correct option is A

For an adiabatic process PVy=kHere y = 3/2 and K = constantPV32=klog⁡P+32log⁡v=log⁡kΔPP+32ΔVV=0ΔVV=−23ΔPPΔVV×100=−23ΔPP×100=−23×23=−49volume decreases by about  49%
