A physical change is a change which affects only the physical properties of an object, not its chemical properties. Examples include breaking glass, smoothing a rock with a sander, and freezing water. As long as a new substance is not created in a process, the process is a physical change.
Melting of an ice cube is an example of a physical change in an object. The ice cube changes from a solid to a liquid state without changing its chemical composition.
Having a section cut off.
grinding any substance would by a physical change, because they are still that object
A physical model is a smaller or larger physical copy of an object. The object being modelled may be small(for example, an atom or cell) or large (for example, the Solar System).
Yes you can, a physical change is when you change an object i.e. you sharpening a pencil is a physical change, you didn't create anything new, just changed it.
Yes. A physical change such as melting, can change a solid, such as ice, into a liquid, water.
no cooked rice is not a physical change but is an example of chemical change as we cant obtain the raw rice after cooking it
a physical change is when the object changes in a way but it is still that same object Example: A piece of bread if u toast (burn) it it will still be bread
An object's size is a physical property of the object.
Because a physical change just alters the appearance of an object, where as a chemical change alters the texture or state of an object.
The changes and constant features in a physical change depend on the object tested. The makeup of the object does not change but the visual may.

Physical changes are changes that only change the appearance of an object, but not the type of matter. For example, if a metal bike rusts the bike will still remain a solid. That is a physical change.
An orange is a physical object and is not any kind of "change"!
An example of physical change is ice melting in to water.
physical change, because you are changing the physical property of the object. you are causing the change by hammering it. If you were to put some kind of chemical on it and it changed the physical property of the object that would be a chemical change.
In a physical change the object changes appearance but in a chemical change the object turns into something different with different properties.
It is physical because the object doesn't chemical change . the object just pushes upward in water of liquid and gas( air) on an object placed in it.
