Take this as a note. A mixture is always a physical change, as you can simply evaporate the water and have Urea again. Chemical change always involves the changing of reaction properties amongst its reactants.
Mixing salt and water is a physical change, not a chemical change. The salt does not change its chemical composition when it dissolves in water, only its physical state.
The fact that isopropyl alcohol mixes with water is a physical property. It is based on the physical interactions between the molecules of isopropyl alcohol and water, without any chemical change taking place.
Physical change as no new substance is formed and the properties have also not changed. Hope it helps!
chemical
Mixing sugar and cinnamon is a physical change, as it does not alter the chemical composition of either substance. A chemical change involves a rearrangement of atoms to form new substances with different properties.
Mixing is a physical process.
Mixing flour and rubbing alcohol is a physical change. In this process, the flour and rubbing alcohol retain their individual properties and can be separated again. There is no chemical reaction occurring, as the composition of the flour and the rubbing alcohol remains unchanged.
Mixing borax and polyvinyl alcohol does not result in a chemical change. Instead, it forms a physical change known as cross-linking, where the borax molecules create bonds with the polyvinyl alcohol molecules to form a flexible slime-like material.
Physical
It depends on what you are mixing it with.
it is a chemical change
physical :)

A simple mixing is a physical process.
