A monoatomic gas is suddenly compressed to(1//8)^(th)ofinitial volume adiabatically . The ratioof its final pressure to the initial volume adiabatically. The ratio of (Given the ratio of the specific heats of the given gas to be 5/3 )

Answer»

32
`40/3 `
`24/5`
8

Solution :for an ADIABATICPROCESS, `PV^(gamma)`= constant
` P_(1)V_(1)^(gamma)=P_(2) V_(2)^(gamma) `
`thereforeP_(2)/P_(1) = (V_(1)/V_(2))^(gamma) = ((8V_(1))/V_(1))^(5/3) =2^(5) = 32 `
