Want this question answered?
physical change
Volume is a physical quantity not a change. However CHANGE in volume is a physical change.
Nope. That is a physical change. a sugar cube that is crushed into powdered sugar is still sugar.
this queston is stupid
Gases change their volume according to the container that they are in. Liquids change shape but not volume, and solids change neither shape nor volume.
It would only change the volume. This is because volume is how much room an object takes up, and crushing the car will make volume smaller. Mass is how much "stuff" an object is made of. So unless like, the bumper falls of, mass stays the same.
The density of the metal doesn't change when you crush a can.
When a aluminum can is crushed, it undergoes a physical change, because even though the object got crushed and misshaped it still has the same identity.The identity has never changed.
Of course. Like anything, when bread is crushed, its density increases. Anything that is crushed will have higher density in its crushed state. The only things that you can crush and NOT (permamently) increase their density are those that return to their original shape after being crushed. The increase in density is due to the fact that there is more bread in a smaller volume. When you squeeze the bread, you squeeze out some of the air, reducing its volume while maintaining its mass. Density = mass/volume.
it is a physical change :-)

i have no idea i asked you!!
Percentage change in volume= Change in volume/intial volume X 100

It is only a physical change.
yes it is physical change but how can it be rewanable thats my question
