Bursting a cracker is not a physical 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.
Origami is a physical change because it involves the folding and manipulation of paper without altering its chemical composition.
A physical change that does not produce a new substance is called a reversible change. This means the change can be undone by reversing the process, such as melting or freezing.
It's a physical change why are some people f$#@%ing stupid and saying a chemical change??
Hardness is a physical change. It does not involve a change in the chemical composition or structure of a substance, but rather a change in its physical properties such as strength or resistance to deformation.
no, bursting of balloons is a physical change as the only change that occurs that that the shape of the balloon changes . Coming out of air is not a chemical change.
Yes, breaking a cracker into half is a physical change because only the physical appearance of the cracker has changed, but its chemical composition remains the same.
The bursting of crackers involves a chemical change, where the chemical composition of the materials in the crackers is altered to produce the sound, light, and heat effects. This process is irreversible.
It is definitely a chemical change
Well a chemical change cannot be reversed while a physical change can be, what do you think??
Changes that take place within seconds are known as fast change. For example bursting of a fire cracker is a fast change and a forest fire can spread very fastly.
A water pipe bursting is a physical reaction. It does not involve any chemical changes in the water itself, but rather a physical change in the structure of the pipe, causing it to break and release the water inside.
The swelling and bursting of a red blood cell placed in distilled water is a physical change. This is because the cell's structure is altered due to the osmotic pressure causing water to move into the cell, leading to swelling and ultimately bursting. No new substances are formed in this process.
It was like a strawberry bursting with flavour
Burning of a cracker is an irreversible change. Once the cracker is burnt, it undergoes a chemical reaction that cannot be easily reversed to its original form.
When water changes state from a liquid to a solid, it is undergoing a physical change. The chemical structure of water is not altered, so no chemical changes have occurred.
