WebIn the video here, Sal uses a horizontal line through the phase diagram. But, it doesn't have to be horizontal. Imagine a vertical line through this diagram-- for water, choose 100 degrees C. As long as you are at 100 C, you can change the phase by changing the pressure on the system. This kind of process is called "adiabatic". 2 comments WebThe nature of the phase change depends on the direction of the heat transfer.

But this is also the same temperature as that substance's freezing point. This is because that specific... Web•When the temperature of the solid reaches its melting point, adding more heat does not change the temperature because all the heat goes into melting the solid. Thus, phase change generally occurs at a constant temperature. •Few exceptions exist, e.g., amorphous solids do not have ordered internal structure, and hence do not have a legal benefits of marriage in california

WebSep 12, 2024 · The phase change from solid to gas is called sublimation. You may have noticed that snow can disappear into thin air without a trace of liquid water, or that ice cubes can disappear in a freezer. Both are examples of sublimation. The reverse also happens: Frost can form on very cold windows without going through the liquid stage.
