when a physical change has occurred the object changes but it can be turned back into what it originally was. When a chemical change has occurred the object changes and it can't be changed back into what it originally was. Physical change ex: when a table breaks you can glue it back together. Chemical change ex: when a bike rusts.
Remember that in a physical change the chemical susbstances never change. That is why we can turn the change back.
chemical change is you can change it once but you can not change to it's oorngle form and physical form you can change it and put it back to it's orngle form
That is the most important fact, you can't change it back.
A color is considered a physical property. It the color changes, it is a chemical change. Why??
because if you put a orange shrit and you put in the washer with bleach
the bleach will eat the color away and that is a chemical change
I like the comparison.
Yup. that is true and that is why people don't put bleach in with colored clothes.
To think how many chemical changes and reactions happen right in our own homes.
In a physical change the substance's physical appearance is being changed but not the substance itself, like folding a paper. In a chemical change you are creating a new substance, like burning a paper where you are creating ash from the paper.
Burning the paper is a chemical change. It turns into ash and smoke. It can't come back. If we fold it we can unfold it again. It is still the same paper.
A physical change is something u can get rid of and bring back chemical change is something that you can get rid of and it won't return
You got it down. One you get back (physical), the other it can't come back(chemical) no matter what you do.
well if you make pancakes that is a chemical change cause you can never get the egg the floor or the butter back,and if you were to crumble a piece of paper its still paper so it a physical change
A chemical change can do many things to turn into a new substance like you could notice it by it bubbling up or the change of its color. An example is when you make a pancake, the batter is turn into a new substance like the pancake. Now an example of a physical property is when you rip a piece of paper you still can get it back by taping it.
it is physical change not physical property when you read it. My bad
You should put the science words on this website.
Mr Conway is the air a chemical change or a physical change?
for a physical change just the appearance is different other than that the substance is the same. for example like when water freezes into ice it is still water just in a different form/state.
Aisah, Jeremy, Alyssa, Axel, Ratana,
It is great to see that you understand about chemical and physical changes. I also like the idea of adding the vocab to the website. I add it for next year.
