What is one major difference in a physical change and a chemical change is?
Physical change, changes the appearance or the surface. Chemical change, changes the minerals inside the object. Physical deals with the appearance and the surface. Chemical changes the structure of the minerals inside the object.
Is fireworks a physical change?
Yes, fireworks involve a chemical reaction where the materials inside the firework combine to produce light, heat, and sound. This chemical reaction is not reversible, so it is considered a chemical change rather than a physical change.
Is blowing up a balloon a physical or chemical change and why?
Blowing up a balloon is a physical change because the air being blown into the balloon does not alter the chemical composition of the balloon material. The change is reversible, as the balloon can be deflated and reinflated multiple times without changing its chemical makeup.
Is breaking a glow stick a chemical or physical change?
It's a chemical change--there's a glass ampule in the glow stick. and it's got one chemical in it. Around it is another chemical. When you break the glow stick the two chemicals mix, and the glow happens.
What is the difference between physical and chemical changes in terms of what happens to the matter involved in each change?
In a physical change, the chemical composition of the substance does not change, it merely changes form. In a chemical change, the chemical formula changes so that fundamental properties such as density and molar mass change.
What physical change happens when you put a balloon in the freezer?
The air inside the balloon will contract, so the balloon will tend to look slightly crinkled.
When frost forms on the inside of the freezer a chemical or physical change?
It is a physical change. When the water vapour inside of the freezer turns to frost (ice), it hasnt changed the fact that it is still water, just in a different form. Therefore, this is a physical change.
Is cracking eggs a chemial change?
Cracking an egg is a physical change, not a chemical change.
What is one major difference in a physical change and a chemical change is?
Physical change, changes the appearance or the surface. Chemical change, changes the minerals inside the object. Physical deals with the appearance and the surface. Chemical changes the structure of the minerals inside the object.
Is cracking eggs a physical or a chemical change?
physical change since the egg and the contents inside do not become a new substance they remain the same only thing is that the shape or the appearance or the physical structure changes that is why it is called as a physical change not chemical because its internal composition is the same
Is fireworks a physical change?
Yes, fireworks involve a chemical reaction where the materials inside the firework combine to produce light, heat, and sound. This chemical reaction is not reversible, so it is considered a chemical change rather than a physical change.
Is egg boiling a physical or chemical change?
The egg actually turns solid inside, so that is a physical change. If the egg turned into a liquid or gas after boiling it then that would be considered "chemical change"
Is blowing up a balloon a physical or chemical change and why?
Blowing up a balloon is a physical change because the air being blown into the balloon does not alter the chemical composition of the balloon material. The change is reversible, as the balloon can be deflated and reinflated multiple times without changing its chemical makeup.
Is a pellet of sodium is sliced in two a physical change or a chemical change?
Physical, because each slice of pellet is still the same chemically: you have merely divided your one sodium block into two blocks of sodium. If it were chemical, some kind of notable chemical difference would have occurred (you would no longer have sodium, but something else).
Explain how breathing on glassis an example of a reversible change?
Breathing on glass is an example of the reversible change because, the air inside the glass can be breathed in again.
What is a physical change as a car ages?
*Paint fades *Scratches *Tires are worn out * Dirtier (inside & out)
