A physical change where a solution is made is when dissolving salt in water to create a saltwater solution. In this process, the salt particles disperse and mix uniformly with water molecules without undergoing a chemical reaction. This results in a clear and homogeneous mixture that can be easily separated by evaporation.

Is mixing sodium chloride and water a chemical or physical change?
Mixing sodium chloride and water is a physical change. The chemical composition of the sodium chloride (NaCl) remains the same in the solution, the sodium chloride molecules are simply dispersed in the water. The change is reversible and does not involve a chemical reaction.
Is bread iodine solution a physical or chemical change?
Mixing bread with iodine solution to observe a color change is a physical change as it does not alter the chemical composition of the bread or the iodine solution. The color change occurs due to a physical interaction between the starch in the bread and the iodine molecules.
Is mixing sugar with iodine solution a chemical change or a physical change?
Mixing sugar with iodine solution is a physical change because no new substances are formed. The sugar and iodine solution retain their individual chemical properties even when mixed together.
Is a solution a physical or chemical change?
A solution is not a change; a solution is represented by a solute dissolved in a solvent; but dissolving (without chemical reaction) is a physical process.
When oil dissolves in gasoline and gives a homogeneous solution is it a chemical change or a physical change?
It is a physical change because no new substances are formed during the dissolving process. The oil and gasoline retain their chemical properties even though they are mixed together at the molecular level to form a homogeneous solution.
Is converting iron to a steel alloy a physical change?
It is a physical change as an alloy is a solid solution made from various metals. As you can still separate these different metals after the alloy is made it is a physical change and not a chemical change.
Does a solution have a chemical change?
A solution does not have a chemical change, but it does have a physical change in state.
Is creating a solution a physical change or a chemical change?
Dissolving is a physical change.
Is a solution a chemical or physical?
A solution is a material not a change; dissolving is a physical process.
Is mixing sodium chloride and water a chemical or physical change?

Is it a physical change when a sugar and water solution is evaporated?
no
Is bread iodine solution a physical or chemical change?
Mixing bread with iodine solution to observe a color change is a physical change as it does not alter the chemical composition of the bread or the iodine solution. The color change occurs due to a physical interaction between the starch in the bread and the iodine molecules.
Is a glass breaking a chemical change?
A chemical change is when the molecules of an object / solution are changed. A physical change is when the object / solution is altered without molecular change. Breaking glass is a physical change.
Is mixing sugar with iodine solution a chemical change or a physical change?
Mixing sugar with iodine solution is a physical change because no new substances are formed. The sugar and iodine solution retain their individual chemical properties even when mixed together.
