Mashing potatoes is a physical change because it does not change the chemical or physical properties of the potatoes.
Crushing creates a physical change in the size of the pieces but it does not change their chemical make up.
yes, theres is not change to it's molecular structure
No, it is a chemical change. The metal oxide formed is a new substance.
yes
Disintegration can be a chemical change, but it depends on what kind it is. For example, sharpening a knife is a physical change, but burning a piece of wood is a chemical change.
Breaking water into the component parts of hydrogen and oxygen is a CHEMICAL change.
This change is a physical change because the matter is made up of the same components that it consisted of before it was broken. An example of a chemical change is the molecular rearrangement of matter like rust on a car.
Because you are just breaking it into smaller pieces. The rock's chemical make up is not being changed.
Yes, as it's still glass. There is no chemical/molecular change.
yes, breaking glass changes the physical properties of the piece, while a chemical change would be removing one of the elements that make up the glass
Oh, dude, it's like a little bit of both! When you chew that juicy burger, the physical action of biting and breaking it down is a physical change. But then your saliva gets all up in there and starts breaking down the food chemically, so that's a chemical change. It's like a party in your mouth, man.
Yes, crumbling something is a physical change. For example, lets say you crumbled up your paper, theoretically, you could always get your completely flat paper back from the crumbled up mess.
Physical.
well breaking things means your tearing things apart. breaking up with your girl friend means you guys are no longer in a mental nor physical relationship
A physical change involves altering the form of a substance, such as changing its shape or state, without breaking the chemical bonds that hold its molecules together. This type of change is reversible and does not result in the formation of a new substance.
