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.
A phase change.
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.
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.
