about 3 billion years after the Big Bang
The amount of atoms stay the same. The element does not change chemically only physically.
During a phase change, atoms interact differently primarily due to changes in energy and the arrangement of particles. For instance, in a solid, atoms are closely packed and vibrate in fixed positions, while in a liquid, they gain energy, allowing them to slide past one another. In gases, atoms are even more energetic and move freely, resulting in minimal interaction. These changes in energy and spatial organization lead to the distinct properties of each phase.

Well, a physical change is one that does not change the identity of a substance. So say if ice melts (a phase change from solid to liquid), it's still water; it hasn't morphed into something else. Phase changes are just changes in the way the molecules (or atoms) are arranged in space.
In two phase locking there are two phases. The first phase is known as Expanding Phase and locks are issued in this phase. No lock is released. Then after change all changes are committed and the second phase starts that is the Shrinking Phase in which all the changes are noted and the locks are released. No locks are issued in this phase
In the solid phase, the atoms are tightly packed in a regular manner. They only vibrate in their own positions. In the liquid phase, the atoms are slightly more disordered and irregularly packed. They can move around freely. In the gaseous phase, the atoms have very large spaces between one another and they can move around at very high speeds.
What is the phase change in evaporation
The atoms movement is either more free (liquid to gas) or more restricted (liquid to solid)
Change of phase is caused 99% of the time by a change in temperature or pressure.
Phase change. Liquid phase to gaseous phase (evaporation) Liquid phase to solid phase (solidification, freezing) Solid phase to gaseous phase (sublimation9 Etc...
During phase changes, energy is either absorbed or released in the form of heat. This energy is used to break or form intermolecular forces between particles. As a result, temperature remains constant during the phase change until all the substance has transitioned to the new phase.
A phase change is an example of a physical change, not a chemical, nuclear, or covalent change. During a phase change, the substance undergoes a change in state (solid, liquid, gas) without any change in its chemical composition.
