  1. Laws of thermodynamics - Wikipedia

    Traditionally, thermodynamics has recognized three fundamental laws, simply named by an ordinal identification, the first law, the second law, and the third law. [1] [2] [3] A more fundamental statement was later labelled as the zeroth law, after the first three laws had been established.

    There are four laws of thermodynamics. They talk about temperature, heat, work, and entropy. They are used in thermodynamics and other sciences, for example chemistry. Thermodynamics had three main laws: the first law, the second law, and the third law. Then there was another law, called the "zeroth law." The law of conservation of mass is also an important idea in thermodynamics, but it is not called a law.

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

  5. First law of thermodynamics - Wikipedia

    The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic processes, distinguishing two kinds of transfer of energy, as heat and as thermodynamic work, and relating them to a function of a body's state, called Internal energy.

  6. First law of thermodynamics - Simple English Wikipedia, the ...

    The first law of thermodynamics states that energy can neither be created nor destroyed; it can changed only from one form to another. The law forms the basis of the principle of conservation of energy. This means that anything that uses energy is changing the energy from one kind of energy to another. For example, exercising changes energy from food into kinetic energy. Another example: In the Sun, Nuclear Fusion changes mass into heat and light, which travels to Earth and is used by plants to

  7. Second law of thermodynamics - Wikipedia

    The second law of thermodynamics establishes the concept of entropy as a physical property of a thermodynamic system.Entropy predicts the direction of spontaneous processes, and determines whether they are irreversible or impossible, despite obeying the requirement of conservation of energy, which is established in the first law of thermodynamics.

  8. Second law of thermodynamics - Simple English Wikipedia, the ...

    The second law of thermodynamics says that when energy changes from one form to another form, or matter moves freely, entropy (disorder) in a closed system increases. Differences in temperature , pressure , and density tend to even out horizontally after a while.

  9. thermodynamics | Laws, Definition, & Equations | Britannica

    Thermodynamics, science of the relationship between heat, work, temperature, and energy. Thermodynamics deals with the transfer of energy from one place to another and from one form to another. The key concept is that heat is a form of energy corresponding to a definite amount of mechanical work.

  10. Thermodynamics Basics. The amount of heat transferred depends upon the speed and motion of the atoms or molecules, as they interact with one another.
