Answer: hope it helps .... mark as brainliest .....

Explanation:

Phase changes typically occur when the temperature or pressure of a system is altered. When temperature or pressure increases, molecules interact more with each other. When pressure increases or temperature decreases, it's easier for atoms and molecules to settle into a more rigid structure. When pressure is released, it's easier for particles to move away from each other.

For example, at normal atmospheric pressure, ice melts as the temperature increases. If you held the temperature steady but lowered the pressure, eventually you would reach a point where the ice would undergo sublimation directly to water vapor.
