Constant pressure process

This ppt is more useful for Civil Engineering students.

I have prepared this ppt during my college days as a part of semester evaluation . Hope this will help to current civil students for their ppt presentations and in many more activities as a part of their semester assessments.

I have prepared this ppt as per the syllabus concerned in the particular topic of the subject, so one can directly use it just by editing their names.

4. An isobaric process is a thermodynamic process in which the pressure stays constant. The term derives from the greek iso -(equal) and baros-(weight). The heat transferred to the system does work,but also changes the internal energy of the system. 4

5. A piston slides to the position where the external pressure and the gas pressure are equal. As long as the external pressure is constant, so must be the gas pressure.

6. A constant-pressure process appears on a pV diagram as a horizontal line. 6

7. For all ideal-gas processes, the work is the area under the pV graph between V i and V f . Fig (a), shows work done by the gas for an isobaric process.

8. Relation between p,V and T: P1V1/T1=P2V2/T2 but p1=p2, So, V1/T1=V2/T2 8 1. If the pressure is held constant, the boundary work equation becomes
