Answer:
This diagram shows the nomenclature for the different phase transitions their reversibility and relation with the enthalpy variation.
In physics and chemistry it is observed that, for any substance or mixture, modifying its conditions of temperature or pressure, different states or phases, called states of aggregation of matter, can be obtained in relation to the binding forces of the particles (molecules, atoms or ions) that destruction.1
All states of aggregation characteristics and different characteristics; the best known and observable on a daily basis are four, called solid, liquid, gaseous2 and plasma phases.3 Other states that do not occur naturally in our environment are also possible, for example: Bose-Einstein condensate, 4 fermionic condensate and stars of neutrons It is believed that others are also possible, such as quarks-gluonas plasma.
