Physical change
A physical change in matter occurs when the shape or form of matter changes, but there is no chemical reaction. If someone were to melt a sugar cube, that would be an example of a physical change.
A physical change only. Its still ice. Even if it melts to water, its still a physical change.Crushing something would result in a physical change.
it would be physical change because physical change is when the substance stays the same
Physical.
physical... the matter itself does not change. That would imply that a chemical change is taking place
Something that burns or is flammable would be a chemical change.
Copper is reshaped, but it's molecular structure does not change ;)
Copper is reshaped, but it’s molecular structure does not change.
The temperature increase from 90 to 100 degrees for heptane would not cause a chemical change. It would only result in a physical change, such as a phase change from liquid to gas.
A physical change is a change that can be undone. A chemical change cannot be undone. An example of this would be dissolving salt in water. This is a physical change because if you let the water in the container evaporate the salt will be left behind. A chemical change would be like burning a piece of wood since you cannot undo the change taking place to the wood.
I am going to assume you are asking about physical changes. For a physical change to take place your internal and external body structure would have to change so in theory yes it would hurt a lot. bones would need to shift and changes places which would certainly cause pinched nerves.It is important to note that a physical change is NOT something that is possible.If you were asking about mental change then there is no physical pain involved with that
Pounding a gold coin into a different shape would probably not effect a chemical change. If, however, the pounding produced enough heat to meal the coin, some chemical change could take place.
Physical change
Physical changes and Chemical changes are both the same - this would be a reversible change.

Crushing a can would be a physical change. It would only change the shape.
