An ideal rigid diatomic gas ( = 7 5 ) undergoes an adiabatic change . If the relation between temperature and volume is TV^x = constant then the value of x is

Step-by-step solution

For an adiabatic process, the relation between temperature and volume is given by TV^ - 1 = constant . Comparing this with the given relation TV^x = constant , we get x = - 1 . Given that the gas is an ideal rigid diatomic gas, = 7 5 . Substituting the value of : x = 7 5 - 1 = 2 5 = 0.40 Answer: 0.40
