Thermodynamics print that page

Carnot_engine_(hot_body_-_working_body_-_cold_body)

Historically, thermodynamics developed out of a desire to increase the efficiency of early steam engines , particularly through the work of French physicist Nicolas Léonard Sadi Carnot (1824) who believed that the efficiency of heat engines was the key that could help France win the Napoleonic

Second law of thermodynamics print that page

The second law of thermodynamics is an expression of the tendency that over time, differences in temperature, pressure, and chemical potential equilibrate in an isolated physical system . From the state of thermodynamic equilibrium , the law deduced the principle of the increase of entropy

Volume (thermodynamics) print that page

In thermodynamics , the volume of a system is an important extensive parameter for describing its thermodynamic state . The specific volume , an intensive property , is the system's volume per unit of mass. Volume is a function of state and is inter-dependant with other thermodynamic properties

Quantum thermodynamics print that page

In the physical sciences, quantum thermodynamics is the study of heat and work dynamics in quantum systems. Approximately, quantum thermodynamics attempts to combine thermodynamics and quantum mechanics into a coherent whole. The essential point at which "quantum mechanics" began was

Statistical mechanics print that page

predictions based on microscopic properties is the main advantage of statistical mechanics over classical thermodynamics . Both theories are governed by the second law of thermodynamics through the medium of entropy. However, entropy in thermodynamics can only be known empirically, whereas

Thermodynamic free energy print that page

The thermodynamic free energy is the amount of work that a thermodynamic system can perform. The concept is useful in the thermodynamics of chemical or thermal processes in engineering and science. The free energy is the internal energy of a system less the amount of energy that cannot

Work (thermodynamics) print that page

In thermodynamics , work performed by a system is the energy transferred by the system to another that is accounted for by changes in the external generalized mechanical constraints on the system. As such, thermodynamic work is a generalization of the concept of mechanical work in mechanics

History of thermodynamics print that page

Savery-engine

The history of thermodynamics is a fundamental strand in the history of physics , the history of chemistry , and the history of science in general. Owing to the relevance of thermodynamics in much of science and technology , its history is finely woven with the developments of classical
