Physical one.
It is a physical change because it is still a sheet of paper.
Physical change. The paper is still a piece of paper; nothing happened to the chemical composition of it.
Thermoforming is an industrial process where you heat a sheet of material to a pliable temperature, then draw it down onto a mold to create a shape. It's a physical change, not a chemical one.
NO, it is a chemical change, because it cannot be reversed.No because it changes shape color Android more so its a physical changeBurning of paper is not a physical change. It is chemical change as ash is formed in the process which is new compound and oxides of carbon are also released during the process. By the definition of chemical change, we come to know that during chemical change a new substance must form. These changes are irreversible in nature.Yes because once you burn a piece of paper you just simply cannot turn it back to a blank sheet.
A physical change is a change that affects the form of a substance without altering its chemical composition. Examples include bending a metal sheet, folding a piece of paper, or tearing a piece of fabric.
A physical change means converting how an object looks or feels. Water changed into ice or water would be a physical change. Breaking, bending, melting, evaporating are all physical changes. A chemical change would be changing an object into something you can't change back. Taking bark off a tree (physical) and burning it is a chemical change. Chemical change means burning, rusting, and combustion. I hope this helped. Nossy
Yes it is a physical change. The only other option is chemical change and the metal didnt change its chemical make up, it only changed its shape, and shape is the only thing that did change.
Hammering gold into a thin foil is a physical process. It involves physically breaking down the gold and flattening it into a thin sheet without any change in its chemical composition. This is in contrast to a chemical process, which would involve altering the gold's chemical structure or composition to create a thin foil.
Reactions that are not chemical reactions are physical reactions. These reactions involve a change in only the physical state of an element, not its chemical properties. Thus, physical changes include freezing, condensation, sublimation, hammering a metal into a sheet, cutting sodium metal, etc.
It is a physical change because it is still a sheet of paper.
These are chemical reactions (changes).
Pounding a sheet of copper into a bowl is a physical change because the copper is still the same substance before and after the change. The change in shape does not alter the chemical composition of the copper.
If the sheet is turning into a pillowcase, it would be a physical change. The sheet is not changing anything but its shape to become a pillowcase, and it most likely can be reversed to turn back into a sheet.
Well, isn't that interesting! The first sheet of paper underwent a physical change when it was torn in half. The second sheet experienced a chemical change when it was burned. And the third sheet went through a physical change when it was crumpled into a ball. Each sheet transformed in its own unique way, just like how every brushstroke creates a beautiful painting.
Physical change. The paper is still a piece of paper; nothing happened to the chemical composition of it.
Well because the paper is flat and when you crumple it, it is changing and getting wrinkly and in a crumpled form,
Depending on the experiment, there will be a series of physical and chemical changes.
