About 100°C heat can cause it to melt(which is a physical change)
For example is melting.
It would be a physical change because you are changing the shape of the wood not the chemical composition of the wood. However, you could possibly create a chemical change if you could hammer hard and long enough to burn the wood. Not likely, but it is possible.
You could separate it all out.
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.
Yes. The way I think about it is if you can change it back (in this case, you could filter the epsom salt out, or evaporate the water, drying it) then it is a physical change.
For example is melting.
The chemical formula of sodium chloride is not changed by dissolution.
it blaw blaw blaw blaw
Yes. Physical changes only cause a substance to change in the appearance. You could measure if it grew in size, if it changed color, the amount of components the substance now contains after the physical change
Well it could either be a physical change OR a chemical change. .
If you are refering to force as a general term, force is the ability to cause physical change. This could be displayed as push or pull.
physical change- solid to solution
