Sketch constant preassure curve in T-s diagram.
The constant pressure and constant volume processes are given by curved lines on t-s diagram and the slope of constant volume process is greater than constant pressure on a t-s plot.
As we can see from the above figure that -
(1) On heat addition process the temperature increases and so does the entropy.
(2) On heat rejection process the temperature decreases and so does the entropy.
Which means that the temperature and entropy are the properties that are associated with the heat changes that take place in a system.
