Aluminum bending is a physical change. This is because the aluminum is still the same aluminum as it was before just in a different shape.
Bending aluminum is a physical change because the internal structure of the aluminum remains the same even though its shape has been altered. Chemical changes involve the formation of new substances with different chemical properties.
its a physical change.

Mixing flour and milk creates a physical change because no new substances are formed. The flour and milk retain their individual chemical properties, and the mixture can be easily separated by physical means such as straining.
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.
No, though it is not easily irreversible like chemical reactions it is mainly a physical change, unless your car set in fire. (Burning is chemical)
Rusting iron is a chemical change because it involves a chemical reaction between iron, oxygen, and water to form iron oxide (rust). This process cannot be easily reversed by physical means.
It depends. Physical can be easily reversed. Chemical is hard, if not impossible to reverse.
If you burn something it is a chemical change, however if you melt of boil it, it is a physical change.
When a kettle is boiled, it is not a chemical change because the water molecules are simply changing state from liquid to gas due to the heat, without any change in their chemical composition. The process is reversible, as the water vapor can condense back into liquid water.
chemical change is easily reversible whilst physical is not reversible
chemical
Yes. Chemical changes are irreversible, but physical changes can easily be changed back
When water boils, it is a physical change.
physical. because you can easily change it back to water form and/or a gas.
A physical reaction is were the current substance can be changed in state and then changed back easily to it's previous state, a chemical reaction is the opposite, it is difficult to change it back to its previous state.
Framing a poster is a physical change because it does not alter the chemical composition of the poster or the frame itself. The poster and frame retain their original properties even though they are now combined.
physical, because it can be easily reversed
No, though it is not easily irreversible like chemical reactions it is mainly a physical change, unless your car set in fire. (Burning is chemical)
