How you draw ts diagram?

To draw a T-S (Temperature-Entropy) diagram, start by labeling the axes: temperature (T) on the vertical axis and entropy (S) on the horizontal axis. Plot the phase boundaries for water, including solid, liquid, and vapor phases, and include critical points and lines such as the melting and boiling lines. Use curves to represent phase changes, like the isothermal and isentropic processes, and ensure that the diagram reflects the thermodynamic properties of the substance being analyzed. Finally, annotate key points and processes to provide clarity on the various thermodynamic states represented.
