The dissolution of purple salt in water is a physical change. During this process, the salt breaks down into its individual ions, but its chemical composition remains unchanged. The color of the salt may also disperse in the water, indicating a physical alteration rather than a chemical reaction. Overall, the process involves a change in state and appearance, but not in the substance itself.
When salt is mixed in with water, they form a solution. Salt is the solute, and water is the solvent.
Boiling of water is a physical process, a change of phase.
A physical change occurs when the composition of a substance does not change. This means the substance retains its chemical identity but may undergo a change in its physical properties like shape, size, or state of matter. Examples include melting, freezing, boiling, or dissolving.
The change that occurred to the water is a physical change. In this case, the water changed from a liquid state to a solid state without altering its chemical composition.

dissolving is a physical change
Dissolving is a physical process.
When salt dissolves in water, it undergoes a physical change, not a chemical change. This is because the chemical composition of salt (NaCl) remains the same before and after dissolving in water. The salt molecules are simply dispersed in the water, forming a homogeneous mixture.
When salt is mixed in with water, they form a solution. Salt is the solute, and water is the solvent.
Dissolving is a process where a solute (such as sugar or salt) breaks down into individual particles and mixes evenly with a solvent (such as water) to form a solution. This occurs at a molecular level as the solvent molecules surround and separate the solute particles. Dissolving is a physical change that can be reversed by evaporating the solvent, leaving behind the solute.
This is a solution.
They don't. The dissolving of salt in water is not the formation of a new compound, but rather merely creating a uniform mixture. It is not a new substance.
A phase change.
No. Dark pink, is red. And red (and blue) makes purple. So it is not a KIND of purple.
A physical change!
It is a physical change when water boils. See also related answers.
Water boiling is a phase change, which is a kind of physical change.
