For a given mass of a gas in an adiabatic change the temperature and pressure are related according to the law:

Answer»

`(P)/(T)=` constant
`PT^(Y)=` constant
`P^(1-Y)T^(Y)=` constant
`P^(Y)T^(1-Y)=` constant

Solution :`PV^(GAMMA)`=const.
Since `V=(RT)/(P)`
`THEREFORE P cdot (P^(gamma)cdot T^(gamma))/(P^(gamma))=" const. "rArr P^(1-gamma) cdot T^(gamma)=` constant
Thus, correct CHOICE is (c ).
