Webt. e. 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. WebAug 30, 2024 · In graph theory, we can use specific types of graphs to model a wide variety of systems in the real world. An undirected graph (left) has edges with no directionality. On the contrary, a directed graph (center) has edges with specific orientations. Finally, a weighted graph (right) has numerical assignments to each edge.
