A decomposition reaction does not involve molecules trading positions. When two different molecules or pairs of molecules change position with one another, the chemical reaction is known as an exchange reaction.
A phase change does NOT chance the total number of molecules. There will be some evaporation and sublimation too. During the time that ice melts there will some molecules that sublimate to water vapor and also some water molecules evaporate to vapor. But the total mass and number of molecules will not change.
Diffusion is the process that explains the movement of molecules from areas of higher concentration to areas of lower concentration over time. After five hours, molecules will have moved and spread out more evenly in the system due to diffusion.
A free-moving molecule refers to a molecule that is not bound to or constrained by other molecules or structures, allowing it to move freely in its environment. This movement can occur in gases, liquids, or even within certain solids, depending on the temperature and conditions. In contrast to molecules in a solid state, which are held in fixed positions, free-moving molecules can collide with one another and change their positions, influencing processes like diffusion and chemical reactions.
In a solid, the molecules are tightly packed in a fixed arrangement, vibrating in place. As the solid melts and becomes a liquid, the molecules gain enough thermal energy to break free from their fixed positions and move more freely. This creates a less ordered structure and results in increased fluidity.
The molecules in a liquid state are strongly attracted to each other but still have enough kinetic energy to move around and change positions. This allows liquids to flow and take the shape of their container.

When a solution is strongly heated in a flame, the atoms and molecules gain kinetic energy, causing them to move faster and collide more frequently. This can lead to increased chemical reactions, vaporization of the solution, and potentially decomposition of the molecules into smaller fragments or different chemical species.

Yes, it does change your orientation. For example: As a 10 year old boy, you were attracted to girls. Then you became attracted to other men as a 25 year old man.

The sun and stars change positions because Earth moves
Strongly Agree
Yes, during a physical change, molecules remain the same. The arrangement and motion of molecules may change, but the actual atoms that make up the molecules do not change.
