If the pressure and density of CO_(2) gas in adiabatic process changes from (P^(1)d) to (P^(1).d^(1)) where P=32 P^(1) than d/d_(1) is equal to

Answer»

<P>`(1/32)^(1.33)`
`(1/32)^(1/1.33)`
`(32)^(1/1.33)`
`(32)^(1/1.4)`

Solution :`PV^(1) = "constant" RARR PV^(y) = P^(1)(V^(1))^(Y) rArr P/P^(1) = (V^(1)V)^(y) = (32 XX P^(1))/P^(1) = (d/d^(1))^(y)`
(As `V propto 1/d`)
`rArr 32 = (d/d^(1))^(y) rArr d/d^(1) = (32)^(1/y) = (32)^(1/1.33)`
Hence, ( c) is the correct option.
