Changes in temperature or pressure are why these phase changes happen, making molecules move differently There are eight phase changes, including freezing, vaporization, and ionization of different states. As the sample cools at constant pressure (150 atm), we move horizontally left on the phase diagram These phase transitions can have broader implications, such as during storm formation or the creation of weather fronts Understanding these transitions leads to more accurate weather forecasting. The liquid methane could flow because the molecules can move around one another, but not apart from one another
If the lake froze, the liquid methane would become a solid. When more energy is supplied (e.g., by raising the temperature), there comes a point at which the particles have enough energy to move around, but not enough energy to separate This is the liquid phase Particles are still in contact, but are able to move around each other. Jean has a sample of a liquid If she changes the liquid's phase by __________ it, the molecules will spread out, allowing the sample to expand and fill a container of any shape or volume.

Watch this video to find out some details about the changes that occur when matter moves from one phase to another As you watch the segment, you might want to check the definitions of specific terms.
