Graph relating temperature and entropy during a thermodynamic process or cycle
In
thermodynamics, a temperature–entropy (T–s) diagram is a
thermodynamic diagram used to
visualize changes to
temperature (T ) and specific
entropy (s) during a
thermodynamic process or
cycle as the
graph of a
curve. It is a useful and common tool, particularly because it helps to visualize the
heat transfer during a process. For
reversible (ideal) processes, the
area under the T–s curve of a process is the heat transferred to the system during that process.

Working fluids are often
categorized on the basis of the shape of their T–s diagram.
An
isentropic process is depicted as a vertical line on a T–s diagram, whereas an
isothermal process is a horizontal line.
