Chemistry: Phase Changes - EntryTest Looking at the phase change diagram for water and following the dashed line at 1 atm, you can see that water would begin as a solid (ice) and melt at 0ºC. All of the water would be in liquid form by the time the temperature reached 75ºC. The second type of phase change graph you might see on the SAT II Chemistry exam is called a heating curve.

List of Phase Changes Between States of Matter - ThoughtCo Matter undergoes phase changes or phase transitions from one state of matter to another. Below is a complete list of the names of these phase changes. The most commonly known phase changes are those six between solids, liquids, and gasses. However, plasma also is a state of matter, so a complete list requires all eight total phase changes.
