physical reaction
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.
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 with milk would be a chemical change because the acid in the lemon juice can curdle the proteins in the milk, leading to a change in the chemical composition of the mixture.
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.
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.
it is physical because there is no new matter will produce(( water+ juice dissolved)) just

No!
physical change
Making popsicles out of juice is primarily a physical change, not a chemical change. When juice is frozen, its state changes from liquid to solid, but the chemical composition of the juice remains the same. The freezing process does not create new substances; it simply alters the physical form of the juice.
Fermenting is a chemical process.

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.
Floating is a physical property, and is not a 'change' in any sense.
