  2. Physical change - Wikipedia

    en.wikipedia.org/wiki/Physical_change

    Physical changes occur when objects or substances undergo a change that does not change their chemical composition. This contrasts with the concept of chemical change in which the composition of a substance changes or one or more substances combine or break up to form new substances. In general a physical change is reversible using physical ...

  3. Metamorphism - Wikipedia

    en.wikipedia.org/wiki/Metamorphism

    Phase change metamorphism is the creating of a new mineral with the same chemical formula as a mineral of the protolith. This involves a rearrangement of the atoms in the crystals. An example is provided by the aluminium silicate minerals, kyanite, andalusite, and sillimanite. All three have the identical composition, Al 2 SiO 5. Kyanite is ...

  4. Stimulus (physiology) - Wikipedia

    en.wikipedia.org/wiki/Stimulus_(physiology)

    In physiology, a stimulus[1] is a change in a living thing's internal or external environment. This change can be detected by an organism or organ using sensitivity, and leads to a physiological reaction. [2] Sensory receptors can receive stimuli from outside the body, as in touch receptors found in the skin or light receptors in the eye, as ...

  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 ...

  6. Electrochemistry - Wikipedia

    en.wikipedia.org/wiki/Electrochemistry

    Electrochemistry. English chemist John Daniell (left) and physicist Michael Faraday (right), both credited as founders of electrochemistry. Electrochemistry is the branch of physical chemistry concerned with the relationship between electrical potential difference and identifiable chemical change. These reactions involve electrons moving via an ...

  7. Chemistry - Wikipedia

    en.wikipedia.org/wiki/Chemistry

    Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.

  8. Physical chemistry - Wikipedia

    en.wikipedia.org/wiki/Physical_chemistry

    t. e. Physical chemistry is the study of macroscopic and microscopic phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibria. Physical chemistry, in contrast to chemical ...

  9. Articular cartilage damage - Wikipedia

    en.wikipedia.org/wiki/Articular_cartilage_damage

    Articular cartilage damage is often the cause of severe pain, knee swelling, substantial reduction in mobility and severe restrictions to one's activities. Over the last decades, however, research has focused on regenerating damaged joints. These regenerative procedures are believed to delay osteoarthritis of injuries on the articular cartilage ...
