What is the chemical change when a paper bag rips?
When a paper bag rips, the chemical composition of the paper does not change. The ripping of the paper bag is a physical change, where the arrangement of the paper fibers is altered, but the chemical bonds between molecules remain the same.
HOW tearing of a paper is a physical change and burning of paper is a chemical changeEXPLAIN?
Tearing the paper - cannot be reversed. Once torn - the paper can never be identical to the original. Burning paper - changes the bonds of the paper molecules.
Is cutting a circle out of a piece of paper a chemical change?
No. It is a physical change because there is no change in the chemical composition of the paper. If you were to burn the paper, that would be a chemical change called combustion, which would turn the paper into carbon dioxide and water, with the release of heat.
When you rip your notebook is that a physical change?
Yes, ripping your notebook is a physical change because the substance (paper) remains the same, only its shape has been altered. The paper molecules are not chemically altered during the ripping process.
Is folding paper a physical change or a chemical change?
Physical.
Is crumpling a sheet a paper a physical or chemical change?
Well because the paper is flat and when you crumple it, it is changing and getting wrinkly and in a crumpled form,
How do you use crumpled in a sentence?
Crumpled is similar to wrinkled. Here is one possible sentence:She crumpled the piece of paper before tossing it into the trash bin.
Will a flat sheet of paper accelerate at the same rate as a crumpled paper?
In a vacuum, both a flat sheet of paper and a crumpled paper would accelerate at the same rate due to gravity. However, air resistance may affect the acceleration of a crumpled paper more than a flat sheet due to differences in surface area and shape, causing the crumpled paper to fall slower.
A sheet of paper is torn in half Another sheet is burned A third sheet of paper is crumpled into a ball What kind of change has each sheet of paper undergone?
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.
How do you use the word crumpled?
You can use the word crumpled to describe something that has been crushed or wrinkled into a disordered shape, often associated with paper or fabric. For example, "He crumpled the paper into a ball and threw it in the trash."
Which has more air resistance the flat paper or the crampled paper?
The crumpled paper has more air resistance because it has a larger surface area compared to the flat paper. The irregular shape of the crumpled paper causes more air to be trapped and create resistance as it moves through the air.
Why will a sheet of paper sink slowly than a cruplred paper?
A sheet of paper sinks more slowly than a crumpled paper because the crumpled paper contains more air pockets, providing buoyancy. As a result, the crumpled paper has a lower overall density than the flat sheet of paper, causing it to sink more slowly.
Why does a sheet of paper fall slower than one that is crumpled into a ball?
A crumpled paper ball has a smaller surface area compared to a flat sheet of paper, which increases air resistance and slows down its fall. The crumpled ball also has more internal air resistance, which further hinders its fall speed.
Does crumpled paper burn faster than flat paper?
Yes, crumpled paper burns faster than flat paper because the crumpled paper has more surface area exposed to the flames, allowing for faster combustion. The increased surface area allows for better airflow and more efficient burning.
Why does a crumpled piece of paper fall faster than a flat piece of paper?
A crumpled piece of paper falls faster than a flat piece due to air resistance. The crumpled paper has a smaller surface area exposed to air compared to the flat paper, reducing the force of air resistance acting on it. This allows the crumpled paper to accelerate faster towards the ground.
What falls fastest a crumpled paper ball or folded paper?
crumbled
Why does crumpled paper fall faster than straight paper?
Crumpled paper falls faster than straight paper due to its increased aerodynamic drag caused by its irregular shape. The turbulent airflow around the crumpled paper creates more resistance, resulting in a faster descent compared to the smoother, more streamlined straight paper.
