Water Phase Changes on a Pressure Chart

Description

Water phase changes can be mapped on a pressure and temperature chart called a phase diagram. These plots show which phase a substance is in at different conditions. They also reveal where phase transitions happen, because the boundary lines mark the temperatures and pressures where two phases coexist.

Transcript

In natura, la materia esiste in tre fasi: solida, liquida e gassosa. La transizione tra le fasi richiede l'equilibrio di fase tra due fasi e avviene a una temperatura specifica per una data pressione.

Queste condizioni possono essere rappresentate graficamente con pressione e temperatura come assi, noto come diagramma di fase.

Un d...
