2. Energy law - Wikipedia

   en.wikipedia.org/wiki/Energy_law

   Furthermore, in Israel there are certain additional laws that deal with the use of energy sources, such as the Natural Gas Sector Law, [56] 5762-2002 which provides the conditions for the development of the natural gas sphere in Israel, and the Electricity Sector Law, 5756–1996, which established the "Public Utility Authority – Electricity ...

3. Thermal physics - Wikipedia

   en.wikipedia.org/wiki/Thermal_physics

   Thermal physics, generally speaking, is the study of the statistical nature of physical systems from an energetic perspective. Starting with the basics of heat and temperature, thermal physics analyzes the first law of thermodynamics and second law of thermodynamics from the statistical perspective, in terms of the number of microstates corresponding to a given macrostate.

5. Gas laws - Wikipedia

   en.wikipedia.org/wiki/Gas_laws

   The laws describing the behaviour of gases under fixed pressure, volume, amount of gas, and absolute temperature conditions are called gas laws.The basic gas laws were discovered by the end of the 18th century when scientists found out that relationships between pressure, volume and temperature of a sample of gas could be obtained which would hold to approximation for all gases.

6. Second law of thermodynamics - Wikipedia

   en.wikipedia.org/wiki/Second_law_of_thermodynamics

   For a similar process at constant temperature and volume, the change in Helmholtz free energy must be negative, <. Thus, a negative value of the change in free energy (G or A) is a necessary condition for a process to be spontaneous. This is the most useful form of the second law of thermodynamics in chemistry, where free-energy changes can be ...

7. Laws of technical systems evolution - Wikipedia

   en.wikipedia.org/wiki/Laws_of_Technical_Systems...

   The law of energy conductivity of the system; As every technical system is a transformer of energy, this energy should circulate freely and efficiently through its 4 main parts (engine, transmission, working element and control element). The transfer of energy can be by substance, field, or substance-field.

8. First law of thermodynamics - Wikipedia

   en.wikipedia.org/wiki/First_law_of_thermodynamics

   The law distinguishes two principal forms of energy transfer, heat and thermodynamic work, that modify a thermodynamic system containing a constant amount of matter. The law also defines the internal energy of a system, an extensive property for taking account of the balance of heat and work in the system. Energy cannot be created or destroyed ...

9. Outline of energy - Wikipedia

   en.wikipedia.org/wiki/Outline_of_energy

   Potential energy – energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors. [3] [4] Elastic energy – energy of deformation of a material (or its container) exhibiting a restorative force; Gravitational energy – potential energy associated with a gravitational field.
