What is that piece of paper that you dip in a chemical and it changes colour?
Litmus paper
Is decaying burning paper physical or chemical change?
The decaying of burning paper involves both physical and chemical changes. When paper burns, it undergoes a chemical change as it reacts with oxygen, producing ash, smoke, and gases like carbon dioxide. The physical change occurs as the paper transforms from a solid to a gas and ash during combustion. Thus, the overall process is primarily a chemical change due to the formation of new substances.
The difference between a physical propeerty and a chemical change?
The difference is when a physical change occurs and the compound or element doesn't change. Like when water boils or melts it still is water just in different form of it. When a Chemical change occurs it completely changes what the element is. Like if paper is burned it is no longer paper. Another thing is when chemical RxN's occur the starting substance can't be reverted back to how it started but when a physical change occurs it can still go back to how it started.
Is bending a paper clip a chemical change?
No, bending a paper clip is a physical change because the material of the paper clip remains the same before and after bending. Chemical changes involve a change in the chemical composition of a substance.
Is cutting paper chemical change?
Original Answer:noMore Detailed Answer:For a chemical change to occur, the structure of the paper has to be modifed at the chemical level. Cutting or tearing separates the paper into multiple parts, but each part is still paper.A good example of a chemical change is when the paper is burned. During burning, the paper changes from paper to ash, and the result is a change in the chemical structure.
Is transfer of typewriter ribbon onto paper a physical or chemical change?
That is a physical change. No chemical reaction occurs during this process.
How are paper products recycled?
Paper products are recycled very easily. The paper is first immersed in a water/chemical solution that dissolves any ink on the paper. It then creates a paper mush very similar to how paper is first created.
Is melting paper clip a physical or chemical change?
Melting a paper clip is a physical change because it does not alter the chemical composition of the paper clip. The paper clip simply changes from a solid state to a liquid state and can be reversed by cooling it back to a solid.
What are the factors that bring about physical and chemical change?
A physical change is a change of state that does not affect the properties of the substance. Example: Ice melting to water. It's still water, just in a different form. A chemical change is a change of properties in a substance, which creates* a new substance. This happens when two substances combine. Example: Lighting a peice of paper on fire. When this happens, the fire and the paper put together creates ash. *Note: You can not create or destroy mass, only change it. Example: If the paper weighed 1 g before it's burning, it will weigh the same after.
Is setting a piece of paper on fire a example of chemical change?
yes because it changes the physical properties of it as a paper by burning
Is ripping up a piece of paper a chemical change?
It is physical because the appearance hasn't changed at all and is the same paper still. For example, if you burned the paper that would be a chemical change because the paper turned into ash and is releasing gas which is a resulting chemical change that has just happened. Hope this helped :) -V
What is the difference between phyical and chemical changes?
A physical change only changes the appearance of an object, it's chemical makeup is still the same. Melting ice doesn't change it to a different object, just a different state. Like if you rip a piece of paper, it's still a piece of paper. But a chemical change changes the makeup of the object. Burning is a chemical change. Once it burns it is no longer paper.
