i have no idea i asked you!!
The change in the crushed can appearance was caused by a physical change. When the can is crushed, the arrangement of its particles is altered, but no new substances are formed.
Crushing chalk is a physical change, not a chemical change. Physical changes alter the form or appearance of a substance without changing its chemical composition. So, when chalk is crushed, it remains the same substance chemically but in a smaller form.
Well you can't put it back together after it's been crushed, so it's a chemical change!
Yes, matter can undergo both physical and chemical changes simultaneously. For example, when a candle burns, the wax undergoes both a physical change (melting) and a chemical change (combustion) at the same time.
Crushing a lump of roll sulfur is a physical change, as the chemical composition of the sulfur remains the same. The process only alters the physical state of the sulfur without changing its chemical properties.
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.
it is a physical change :-)
In a physical change, materials undergo a change in their physical state or appearance without changing their chemical composition. This can include changes in shape, size, phase (solid, liquid, gas), or state (melting, freezing, evaporating). Physical changes are usually reversible.
It is only a physical change.
Matter can undergo go both physical and chemical change.
Hg is not a change, it is an element. It can undergo changes, both physical and chemical.
The change in the crushed can appearance was caused by a physical change. When the can is crushed, the arrangement of its particles is altered, but no new substances are formed.

No. It is a chemical change.
Bread is not a change. It is a mixture of substances that can undergo physical and chemical changes.
Magnesium is not a change of any sort. It is a metallic element that can undergo both physical an chemical changes.
It is a physical phenomenon.
