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

For an adiabatic process, PVγ = KHere, γ = 32  and K = constant      PV32 = Klog P + 32log V = o log K∴ ∆PP+32∆VV = 0∴  ∆VV = -23∆PP∆VV×100 = -(23)(∆PP×100)% = -23×23% = -49%∴  Volume decreases by about 49%.
