For each phase transition, energy has to be put in to change the "hold" to something less strong.

In contemporary science, this process is known as a phase transition.

But there is a third regime a phase transition away.

This is well known from the theory of phase transitions.

Therefore they would not have phase transitions as one sees in the states of matter.

Any addition of thermal energy results in a phase transition.

James is widely known for his research in phase transitions.

A state of matter is also characterized by phase transitions.

Below the lower critical dimension there is no phase transition.

After a phase transition, a liquid can turn into a crystal.
