A cyclic process is shown in the figure....

A cyclic process is shown in the figure. For the process `AB` which of the following statement is correct ?

A

Heat given to the system will be always `-ve` throughout the process

B

Heat given to the system will be always `+ve` throughout the process

C

First the heat given is `+ve` then `-ve`

D

First the heat given is `-ve` then `+ve`

Text Solution

Verified by Experts

For the process `A to B`
`p=2p_(0)-(p_(0))/(V_(0))(V-V_(0))`
`p=3p_(0)-(p_(0)V)/(V_(0))`
`T=(pV)/(nR)=(1)/(nR)(3p_(0)V-(p_(0))/(V_(0))V^(2))`
`(dT)/(dV)=0rArr 3p_(0)=(p_(0)V)/(V_(0))xx2VrArrV=(3)/(2)V_(0)`
