Water Phase Changes

I'm sharing this because it illustrates exactly what happens to water as we vary its temperature by adding or removing heat, including the types of heat necessary to vary the temperature and change its phase:

Just a reminder:

32ºF = 0ºC
212ºF = 100ºC

Attention to the fact that we have two types of heat:

• Sensible heat: what alters the temperature of the substance
• Latent heat: what breaks or unites molecules, at constant temperature, allowing gradual phase change till they are all completely separated or united, when the temperature begins to vary again

Summarizing, when the water is getting its phase changed, during all the process, the temperature remains constant, and the energy being added to it or removed from it is responsible for breaking the agglutination of molecules or for agglutinating the molecules, respectively.

Including the 4th state of matter, Plasma, look at the names the phase changes receive:

In Portuguese, they are:

• Freezing: Solidificação
• Melting: Fusão
• Vaporization: Vaporização, Ebulição, Calefação
• Condensation: Condensação (vapor), Liquefação (gás)
• Sublimation: Sublimação
• Deposition: Deposição
• Ionization: Ionização
• Deionization: Deonização
