Physical advantages - 1) Plastic is renewable and even after recycling its quality does not decrease.

physical change
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.
physical change
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.
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."
no its just physical change
No, texture is a physical property of a plastic spatula. Chemical properties describe the behavior of a substance in reactions and interactions with other substances.
Some advantages of using plastic bearings are that it saves money, it has corrosion and chemical resistance, designed to maintain a low COF, no messy lubrication and resistance to dirt.
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.
chemical change.because once the tray melts it's no longer there anymore
Now are known hundreds types of plastic materials, different by chemical, physical and mechanical properties.
