Yes, squeezing a lemon is a physical change because it doesn't alter the chemical composition of the lemon. The action of squeezing merely changes the lemon's shape and form, but its chemical makeup remains the same.
Adding lemon to water is considered a reversible change because the lemon can be easily separated from the water by filtration or evaporation, leaving behind the original components of water and lemon. The lemon juice can be extracted again from the lemon by squeezing it, showing that the change is reversible.
It is a physical change
Squeezing lemon juice on fruit to prevent browning is not a chemical reaction, but rather a physical reaction. The citric acid in the lemon juice slows down the oxidation process that causes the fruit to turn brown by acting as an antioxidant.
Juicing a lemon is a physical change because the lemon's molecules remain the same even though its physical form changes from solid to liquid. The process of juicing just separates the juice from the pulp without altering the chemical composition of the lemon.
The cloudiness in tea when lemon is added is due to the reaction between the tannins in the tea and the citric acid in the lemon juice. This reaction causes the proteins in the tea to precipitate out of solution, resulting in the cloudiness. It is a physical change because the appearance of the tea is altered, but the chemical composition of the substances remains the same.
It's a physical change why are some people f$#@%ing stupid and saying a chemical change??

No, it is a physical change.
Adding lemon to water is considered a reversible change because the lemon can be easily separated from the water by filtration or evaporation, leaving behind the original components of water and lemon. The lemon juice can be extracted again from the lemon by squeezing it, showing that the change is reversible.
It is a physical change
Adding lemon to tea is a physical change because no new substances are formed. The lemon flavor simply interacts with the tea molecules in a physical way.
chemical, you can't take the lemon out
Squeezing lemon juice on fruit to prevent browning is not a chemical reaction, but rather a physical reaction. The citric acid in the lemon juice slows down the oxidation process that causes the fruit to turn brown by acting as an antioxidant.
When squeezing a lemon, the force applied comes from the muscles in your hand and arm. By contracting these muscles, you generate the pressure needed to squeeze out the juice from the lemon.
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.
Juicing a lemon is a physical change because the lemon's molecules remain the same even though its physical form changes from solid to liquid. The process of juicing just separates the juice from the pulp without altering the chemical composition of the lemon.
Squeezing clay is is physical. This is something that you can feel and see.
