From the early days of quantum mechanics, scientists have thought that all particles can be categorized into one of two ...

The particles in solids, liquids and gases change arrangement and motion when a substance is heated or cooled down. This is explained by the kinetic theory of matter. Read more about the states of ...

liquids and gases study guide and the states of matter study guide. In a system, the energy of the particles, which can be atoms or molecules, is known as the internal energy. It is the sum of the ...

What makes up the matter we perceive in the universe? To start, there are the usual suspects, like electrons, protons, quarks and neutrinos. But if those particles aren't strange enough for you ...

P. D. Heterogeneous oxidation of atmospheric aerosol particles by gas-phase radicals ... Research Triangle Park, NC: United States Environmental Protection Agency, 1985. Kulmala, M.

In a study, physicists now observed a class of quantum particles called fractional excitons, which behave in unexpected ways and could significantly expand scientists' understanding of the quantum ...

Dark matter is an enigmatic invisible substance supplying five-sixths of the matter of the universe. Unlike photons, the particles of light, the particles of dark matter need to have non-zero mass ...

No material is more volatile than antimatter, which is made of particles of equal mass but opposite charge to normal matter, so things like anti-protons and positrons, which are the antimatter ...

What is a Bose-Einstein Condensate? A Bose-Einstein condensate (BEC) is an exotic state of matter that forms when a dilute gas of bosonic particles is cooled to temperatures very close to absolute ...
