An idealgas (C_(P)//C_(V)=gamma)is expandedso that the amountof heattransferredto thegas theis equalto the decreasein itsinternalenergy .Whatis therelationshipbetweentemperatureand volumeof gasin thisprocess?

Answer»

`T. V^(2(gamma-1))= "constant"`
`T. V^(gamma-1)= "constant"`
`T. V^((gamma-1//2))= "constant"`
`T. V^(gamma)= "constant"`

SOLUTION :`DQ = dU +p dV`
`- dU = dU + pdV`
`- 2n C_(V)DT=(nRT)/(V) d V`
`int(dT)/(T)= (R)/(2C_(V))int(dV)/(V)+ "constant"`
`therefore T V ^(gamma-1)="constant"`
