Isobaric processes are represented by straight lines on: a. p-v diagrams b. t-s diagrams 6. c. t-v diagrams d. η-r diagrams

a)P-v

Explanation:

Isobaric:

 Isobaric process is a process in which initial and final pressure will be same.This is also called constant pressure process.

If we take a process in which pressure is constant then there will be two possibility maybe this is compression process or maybe this is expansion pressure depending on the given condition.

In general only in P-v diagram ,isobaric processes are represented by straight lines.

If we take a saturated steam ,in which on T-s diagram pressure lines are represented by straight lines.

If we take the ideal gas Pv= mRT if we fix pressure then T-v digram will be linear diagram so we can say that here is also isobaric processes are represented by straight lines.

But from above most appropriate  answer will be a.

answer:

sure does
