Mixing juice crystal in water is a physical change because no new substances are formed; only the physical state of the juice crystal changes as it dissolves in the water. It can be reversed by evaporating the water.
Mixing lemon juice and milk would result in a physical change. The two substances retain their original properties and do not create a new chemical compound when mixed together.
Squeezing oranges for juice is not a chemical change because it does not alter the chemical composition of the oranges. It is a physical change where the oranges are only being mechanically processed to extract the juice. The same chemical components of the oranges remain in the juice.
Putting a penny in lemon juice would cause a chemical change because the lemon juice reacts with the copper in the penny to create copper oxide, which changes the chemical composition of the penny.
Dipping blue litmus paper in lemon juice is a chemical change. The acidic nature of lemon juice causes a chemical reaction with the blue litmus paper, turning it red. This change in color indicates a chemical transformation of the litmus paper due to the interaction with the acid in the lemon juice.

Mixing lemon juice and milk would result in a physical change. The two substances retain their original properties and do not create a new chemical compound when mixed together.
it is physical because there is no new matter will produce(( water+ juice dissolved)) just

No!

Fermenting is a chemical process.
Chemical change.
Making diluting juice is a physical change because it involves mixing a concentrated juice with water, resulting in a new mixture without altering the chemical composition of the juice or water. The process is reversible; if the mixture is separated, the original components can be recovered. Additionally, the properties of the juice, such as taste and color, change, but the substances themselves remain unchanged at the molecular level.
It is a physical change. If the substance being made is completely irreversible from the substance you started with it's chemical, but if not, it's physical. Even though it would be difficult, it is possible to get the sugar, lemon juice and water separate again, therefore it's physical.
it is a chemical
Grape juice contains mostly glucose (C6H12O6) and wine also has ethanol (C2H5OH). The ethanol is produced by fermentation of glucose by yeast cells. This is a chemical change.
