  2. Energy transformation - Wikipedia

    en.wikipedia.org/wiki/Energy_transformation

    Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. [1] In physics, energy is a quantity that provides the capacity to perform work or moving (e.g. lifting an object) or provides heat. In addition to being converted, according to the law of conservation of energy, energy is ...

  3. Energy - Wikipedia

    en.wikipedia.org/wiki/Energy

    equal amount of energy carried by matter that is moving from one system to another. A turbo generator transforms the energy of pressurized steam into electrical energy. Energy may be transformed between different forms at various efficiencies. Items that transform between these forms are called transducers.

  4. First law of thermodynamics - Wikipedia

    en.wikipedia.org/wiki/First_law_of_thermodynamics

    e. The first law of thermodynamics is a formulation of the law of conservation of energy in the context of thermodynamic processes. 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 ...

  5. Thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Thermodynamics

    Thermodynamics is a branch of physics that deals with heat, work, and temperature, and their relation to energy, entropy, and the physical properties of matter and radiation. The behavior of these quantities is governed by the four laws of thermodynamics, which convey a quantitative description using measurable macroscopic physical quantities ...

    en.wikipedia.org/wiki/Outline_of_energy

    Energy transformation, relating to energy's changes from one form to another. Energy (signal processing), the inner product of a signal in the time domain; Energy density spectrum, relating to the distribution of signal energy over frequencies. Potential energy, the form of energy that is due to position of an object; Kinetic energy, the form ...

  7. Thermodynamic free energy - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_free_energy

    v. t. e. In thermodynamics, the thermodynamic free energy is one of the state functions of a thermodynamic system (the others being internal energy, enthalpy, entropy, etc.). The change in the free energy is the maximum amount of work that the system can perform in a process at constant temperature, and its sign indicates whether the process is ...
