Crushing a can would be a physical change. It would only change the shape.
No, crushing sodium carbonate does not produce a new chemical substance. Thus, crushing is an example of a physical change.
Crushing an aspirin is a physical change because the small pieces are still chemically the same as the aspirin tablet.
No. Crushing is a physical change.
Crushing an aluminum can is a physical change because the substance itself (aluminum) remains the same before and after crushing. The change in shape and size does not alter the chemical composition of the can.
Crushing a rock is a physical change. It is still rock, just in smaller bits.
Yes, crushing biscuits into crumbs is a physical change. This process alters the size and shape of the biscuits but does not change their chemical composition. The ingredients remain the same, and no new substances are formed as a result of crushing.
Physical
Yes. Physical change is when you change the appearance but not the actual object. Crushing an aluminum can is a physical change because you have only changed its shape, but not its chemical composition.
Crushing a piece of chalk is only a physical change. Chemically, it is still chalk.
Crushing a soda can is a physical change because the substance itself (aluminum) is not altered chemically. The can's shape changes, but its chemical composition remains the same.
Crushing a leaf is a physical change, not a chemical change because the chemical composition of the leaf remains the same before and after crushing. However, if the crushing process causes the leaf to release certain chemicals due to breaking of cell walls, then it can result in a chemical change.
Yes, crushing rocks is considered a physical change because the rocks are broken down into smaller pieces without changing their chemical composition. This process can be reversed by reassembling the pieces back together.
