chemical reactin
It depends what happened to the glass of juice...? An object is not a change =P
Squeezing oranges for juice is a physical change. The physical and chemical properties of the orange do not change.
physical reaction
The process of juice freezing and forming popsicles is a physical change. This is because the change in state from liquid to solid is a physical change that can be easily reversed by allowing the popsicle to thaw back into liquid form.
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.

it is physical because there is no new matter will produce(( water+ juice dissolved)) just

No!

Yes, fermenting fruit juice is a chemical change.
Fermenting is a chemical process.
Chemical change.
physical reaction
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.
