WebThe VT diagram shows: In the segment AB the volume of the gas is directly proportional to the temperature. This means that in this phase the pressure is constant, it is an isobaric process. In the pV diagram it is represented by a horizontal line. We can see that the volume in the first phase (from A to B) increases.
