We distinguish between the states of matter: gas, liquid and solid. Possibly we could add the plasma state and/or the superconductive state as new states of matter. Phase transistions at certain temperature perhaps with some other conditions should have to exist. What do you think, does it make sense?

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.

Yes, there are other phases of matter besides solid, liquid, gas, and phase transitions between these other phases work in a similar way to transitions between the more familiar phases. As another example, helium undergoes a phase transition between a "normal" fluid and a superfluid at a temperature of about 2 K. |

A phase transition is a Thermodynamic (therefore bulk matter) concept which pertains to abrupt changes in the physical properties of a system which occur on a boundary of a Phase Diagram. In the classic case this Phase Diagram has axes for Temperature and Pressure. Water has the three classic phases, plus a "supercritical" region above the critical point. In the case of Superconductivity the physical change occurs on the temperature conductivity graph, but as remarked in another Answer this is not a phase transition universal to all matter. |
