No, making plastic containers is a chemical change as it involves the conversion of raw materials (such as polymers) into a new substance (plastic containers) through a chemical reaction. Physical changes only alter the appearance or physical state of a substance without changing its chemical composition.
no its just physical change
it is a physical change most of the times because you can get i back into its original form. for ice, or plastic... its physical. but for styrofoam, its a chemical change because you cant get it back.
You've got another "chemical change here." One more and you've got a grand slam!
no because all you are doing is changing the shape and form
it is a chemical change and i think maybe it is because you use heat to melt it and metal to shape it.
Crushing a plastic bottle is a physical change, not a physical reaction. This is because the plastic's chemical composition remains the same even though its physical form has changed.
Stretching a piece of plastic until it breaks is a physical change because the bonds between the plastic molecules are being rearranged and broken without changing the chemical composition of the plastic itself.
Yes, burning (oxidation) is chemical change.
If you mean that something is demonstrating plasticity, that would be a physical change.If you mean that plastic (a substance) is being formed, that's a chemical change.However, "plastic" itself is not really a change of any kind, so the best answer is "No."
