15.1. The First Law of Thermodynamics • Define the first law of thermodynamics. • Describe how conservation of energy relates to the first law of thermodynamics. • Identify instances of the first law of thermodynamics working in everyday situations, including biological metabolism. • Calculate changes in the internal energy of a system, after accounting for heat transfer and work done. 15.2. Th...

Abstract We study the thermodynamic performance of a finite-time non-regenerative quantum Stirling-like cycle used as heat engine. consider specifically case in which working substance (WS) is two-level system (TLS). The Stirling made two isochoric transformations separated by compression and an expansion stroke during WS contact with thermal reservoir. To describe these strokes we derive non-M...
