  2. Matter wave - Wikipedia

    en.wikipedia.org/wiki/Matter_wave

    Quantum mechanics. Matter waves are a central part of the theory of quantum mechanics, being half of wave–particle duality. At all scales where measurements have been practical, matter exhibits wave -like behavior. For example, a beam of electrons can be diffracted just like a beam of light or a water wave.

  3. Matter - Wikipedia

    en.wikipedia.org/wiki/Matter

    Matter is a general term describing any 'physical substance'. By contrast, mass is not a substance but rather a quantitative property of matter and other substances or systems; various types of mass are defined within physics – including but not limited to rest mass, inertial mass, relativistic mass, mass–energy.

    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.

  6. List of states of matter - Wikipedia

    en.wikipedia.org/wiki/List_of_states_of_matter

    List of states of matter. Matter organizes into various phases or states of matter depending on its constituents and external factors like pressure and temperature. In common temperatures and pressures, atoms form the three classical states of matter: solid, liquid and gas. Complex molecules can also form various mesophases such as liquid ...

  7. State of matter - Wikipedia

    en.wikipedia.org/wiki/State_of_matter

    In physics, a state of matter is one of the distinct forms in which matter can exist. Four states of matter are observable in everyday life: solid, liquid, gas, and plasma. Many intermediate states are known to exist, such as liquid crystal, and some states only exist under extreme conditions, such as Bose–Einstein condensates and Fermionic ...

  8. Matter creation - Wikipedia

    en.wikipedia.org/wiki/Matter_creation

    In this sense, matter and antimatter particles (such as an electron and a positron) are identified beforehand. The process inverse to particle annihilation can be called matter creation; more precisely, we are considering here the process obtained under time reversal of the annihilation process. This process is also known as pair production ...
