Is making a pitcher of orange juice physical change from concentrate?

When orange juice concentrate is mixed with water, the solute particles (sugar, citric acid, etc.) in the concentrate dissolve in the water molecules. This process is called dissolution, and it is a chemical change because the composition of the mixture has changed. The original concentrate and water are no longer present in their pure forms, but have instead combined to form a new substance: orange juice.

Physical changes, on the other hand, are changes in the form or appearance of a substance without changing its chemical composition. For example, melting ice is a physical change because the water molecules are still present, just in a different form (liquid instead of solid).
