In an isobaric process, the ratio of heat supplied to the system (dQ) and work done by the system (dW) for diatomic gas is

Answer»

`1 : 1`
`7 : 2`
`7 : 5`
`5 : 7`

Solution :`-(dQ)/(DW)=(dQ)/(dQ-dE), dE=dW+dQ, -dW=dQ-dE`
`=(nc_(p)DT)/(nc_(p)dT-nc_(v)dT)=(c_(p))/((c_(p)-c_(v)))`
`=(7R)/(2R){"for diatomic of gas "c_(p)=(7R)/(2)}`.
