Physical state

What is an aggregate state? Definition and explanation ...

Of the Physical state describes the pressure and temperature-dependent state of a chemical substance. The three classical aggregate states solid, liquid and gaseous show physical properties which are typical for the respective state of aggregation with regard to particle movement or particle spacing. In addition to these three states of aggregation, there are a few more in physics, such as the plasma, the Bose-Einstein condensate or the fermion condensate. These are not discussed in detail in the article.
solid (fixed): are in a fixed form. The atoms are relatively fixed due to bonds (e.g., metallic bonding) and, at most, can be made to vibrate but remain in position.
liquids (liquid): the molecules are close to each other, but very variable in movement and can displace each other. As the temperature increases, so does the potential motion of the particles due to Brownian motion.
gases (gaseous): the distance between the atoms is greatest for gases. There are virtually no bonds between the individual atoms.

Phase transitions:

The transition of a substance from one state of aggregation to another state of aggregation is known as Phase transition, The individual phase transitions are shown graphically below.

Evaporate (Phase transition from liquid to gaseous)
Condense (Phase transition from gaseous to liquid)
congeal (Phase transition from liquid to solid)
Melt (Phase transition from solid to liquid)
Sublimate (Phase transition from solid to gaseous)
resublimation (Phase transition from gaseous to solid)
