An equimolar mixture of a mono atomic and diatomic gas is subjected to continuous expernsions such that dQ=(1)/(3)dU+(1)/(2)dW. The equation of the process in terms of the variable P & V will be

Answer»

`PV^(5//4)`=constant
`PV^(11//8)`=constant
`PV^(8//3)`=constant
`PV^(9//4)`= constant

Solution :`DQ=(1)/(3)du+(1)/(2)dw`
From `1^(ST)` LAW of THERMODYNAMICS,
`dQ=du+dw`
`dQ=ncdt. C=®/(gamma-1)+(R )/(1-n)` for `PV^(n)` process.
