Why is popping a balloon an example of a physical change?
Popping a balloon is a physical change because the balloon retains its original chemical composition even after it has been popped. The change is reversible, as the pieces of the popped balloon can be put back together and reinflated.
Is cutting your hair a physcial change?
Yes it is... The hair will grow back,but you're changing the physical appearance by cutting it. Chemically - it's still hair.
Did the balloon changed size?
No, the balloon did not change size.
Why does a balloon burst when near some hot air?
The answer is fairly simple, while some believe that a balloon bursts when near hot air because the balloon simple melts, it actually has to do with the pressure inside the balloon. When near hot air, the air inside the balloon expands slightly, causing a change in pressure, and causing the balloon to burst.
A change in Matter where it's identity does not change?
This is called a physical change. If a new compound is formed, its called a chemical change.
Is breaking a balloon a physical or chemical change?
physical change
Is a balloon breaking a physical or chemical change?
A balloon breaking is a physical change because the bonds between the molecules of the balloon are simply being broken, changing its physical form, but not changing the chemical makeup of the materials involved.
Is cookies considered a chemical change?
No But It Is Considered To Be A Physcial Change
Is a soft cushion a chemical change?
No. It's a physcial property
What is the difference between a chemical and a physcial change?
chemical change is easily reversible whilst physical is not reversible
Is a broken balloon a physical or chemical change?
Physical, because the balloon did not have a change in its chemical composition when it broke.
Is breaking a balloon a physical change?
Yes, it is a physical change. Nothing chemically changed about the balloon.
What are physcial changes?
physcial change is is when something changing its form but it is still the same.
Is breaking glass chemical or physical?
Breaking glass is a physical change, as it does not change the chemical composition of the material.
Is breaking down a physical or a chemical properties?
Since in breaking down there is no chemical change it's a physical change
Is the breaking down of molecules a chemical or physical change?
It is a chemical change.
Is burning a balloon a physical or chemical change?
When thinking of a balloon, it's best to think of two different chemical compounds that do not mix, the balloon itself and air. What makes the balloon pop is that the pressure of the air exceeds the force of the chemical bonds of the balloon. In order for a chemical reaction to take place, you need to start off with one set of chemicals that become a new set of chemicals.However, when a balloon pops, no new chemicals are created. All that happens is that the electron bonds of the compound we know of as the balloon break.
