Summary: The physical state of matter

\n\n personal give tongue to of thing (from Lat. Aggrego-joins associate), the state of the similar substance, the transitions between which be accompanied by an crisp multifariousness in its abandon energy, entropy, density and some some other(prenominal) physical properties. entirely \nsubstances (with some exceptions) so-and-so exist in three states - solid, crystal clear and assaileous. Thus, water at normal mash p = 10l = 325 Pa 760 mm Hg and at a temperature t = 00 C. crystallizes to ice, and at 100 C and boils converted into steam. The wiz-quarter state of reckon is often considered the plasma. \n res publica of matter depends on the physical conditions in which they atomic number 18 find mainly on the temperature and the pressure. Determining a dimension of the norm shelter of the potential drop energy of fundamental interaction of molecules to their average energizing energy. Thus, the solid tela this ratio is greater than 1, less(prenominal) than 1 for gas and liquid is near 1. Transition from one \nphysical state of matter to a nonher accompanied by an abrupt alternate in the value of this ratio associated with an abrupt change intermolecular distances and intermolecular interactions. In gases, the intermolecular distances are large, the molecules do not interact with to each one other and instigate almost freely, plectron the entire volume. In liquids and solids-condensed matter - molecules (atoms) are much side by side(predicate) to each other and interact strongly.
