The pressure and density of a gas (gamma=1.5) changes for (P,rho) to (P',rho') during adiabatic changes if rho'//rho=32, then P'//Pwill be

Answer»

128
1//128
32
1//32

Solution :`PV^(V)=P'V'^(v)RHO = M/V ,V = M/rho`
`P(M/rho)^(v)=rho'(M/rho')^(v)`
`P/rho'=(P')/(rho'^(v)),((rho')/(rho))^(v)=(P')/P, (P')/P=(32)^(1.5)`
`(P')/P=(2^(5))^(3//2)`
`(P')/P=2^(15//2`
