summary: grinding - physical change folding - physical change ductility - physical change melting - physical change fermentation - chemical change combustion - chemical change oxidation - chemical change electrolysis - chemical change chemical changes: a change in a substance that involves a change in identity or chemical makeup of that substance. they are accompanied by a physical change. physical changes: changes in a substance that do NOT involve a change in the identity or chemical makeup of that substance.
Lol I know that I'm three years late, but the simplest way that I can explain it is that physical change temporarily changes the state of an element/compound while chemical change permanently changes the state of an element/compound. For example, if you melt a pen, you will still have the plastic that made up the pen. If you burn the pen, however, you'll get chemical change since all the compounds that make up the pen will become a gas and the only thing you'll have left on the ground is black carbon.
great video. thanks x 100000 who else here is online schooling and their teacher made them watch this? This is how many people are in this situation | |
Then wouldn’t peanut butter be a chemical change since you need to mix it with another substance to make it into peanut butter therefore changing its chemical substance?
nope because physical change occurs when 2 or more substances are dissolved in one another. Also natural peanut butter is just grind up peanuts which mean it had just gone through a change of state( solid to liquid)
There is a physical change and the salt is dissolved, but you didn't create a new substance, you can still boil the water out and get salt. Therefore it is not chemical, but a physical change.

Thank you

Honestly I’m just studying for an exam but this taught me better than actual school...

Who else is here because of homework
And what’s wrong I am here bc of a hw if that bothers u just don’t look at the comments.
Good video. Very basic stuff, but you add things that most people don't know.. Even with a decent chemistry background.
greaaat video, tomorrow is my exam of chemistry and French here in Mx pray 4 me
just curious on how the exam went lmao
Tmr is my math and chem test pls pray for me
Tommyisme how’d that go
Like if this is for homework lol
Nerd
Its dat boi alex he literally just did
@@havoc5438 how is he a nerd doing this for homework I suppose your the nerd for coming with your own free time
random guy /random dimensions Bro it’s a joke , and I only watched this video because my teacher told me to
@@havoc5438 how is it funny calling someone a nerd?
Thank you so much! You make online learning endurable.

who else here is online schooling and their teacher made them watch this?
This is how many people are in this situation

I'm using this for an assignment we have to do its really helpful and giving me ideas on how it becomes physical and a chemical change
So helpful for the homeschooled 3rd grader! We loved your video, it was incredibly helpful!! Thank you.
Amanda McDaniel this is kinda useless a that age and your gonna forget it so
@@hamburgerdan101 Not if you continue teaching chemistry from then the highschool
This comment pissed me off. Im a 10th grader studying for an exam trmw :.
Thxs , It helped me for my Olympiad exam

nope because physical change occurs when 2 or more substances are dissolved in one another. Also natural peanut butter is just grind up peanuts which mean it had just gone through a change of state( solid to liquid)
when you grind peanuts into peanut butter, the peanuts themselves have oil inside them, so technically you do not need to mix in anything else
I was just thinking that
Phuhk when I chew them it’s not peanut butter 🧐
Thank you !! Your wonderful at explaining
Suggested by school.........thought it would be hard,but turned out very simple🤗🤗.......Thnks😇

thank you for this really helpful video!❤
faria hafiz
thnx this helps a lot hopefully it helps me on a test
Uf you scratch the paper with half is a physical change
If the car is rusting is a chemical change is that right?
Sent here by my science teacher :)
This is so helpful! Thank you.
Great video (I made the 1,000 like)👍
That video is great ! Thank you so much
coming in clutch with the three parter my goat
what about the change that occurs when salt is dissolved in water. NaCl plus H 2 O -----> ?
Plz respond. thank you.
There is a physical change and the salt is dissolved, but you didn't create a new substance, you can still boil the water out and get salt. Therefore it is not chemical, but a physical change.
no
I really love this video
I will use this for our Chemistry program in Russia!! HOORAAA
Thanks for helping me with my homework
I will have my exam on thursday entrance exam i wish this topic is included
Thx I needed this for my science test
omg thank youuuuuuu
Very helpful. Thank you VERYYY much
Anyone else doing this for online school?
Chaddy - Brawl Stars yes I’m being forced
This was amazing. :)
Is Flash point a physical or chemical property?
This was very helpful. Thanks!
Tomorrow is my exam thank you
Quarantine brought me here.
kind of confusing but surely somewhat helpful!
This helped a lot
Using video for studying quiz, hop it's helpful
+Tyler Dang let me know if it is
Chem Academy
Thx sir for u r information
Very good explain i understand thx soo much
Please someone tell me that your chemistry teacher told you to watch this video for physical and chemical changes quarantine things 🤦♀️🌝
Thanks m8. this vid was dope with helping me with my science work
Grinding peanuts will make small peanut particles. Peanut butter has so much more in it such as salt and sweeteners.
can you please tell me where can i find this powerpoint ??

what about color? is it physical or chemical?
it'd be chemical, because the matter itself isn't being changed, only its color is
Thanks really informing

Thank you so much! This was very helpful for my upcoming test! (Bro these NPC’s in the comments bruh)
What about if we apply heat to a substance, for example, Calcium carbonate and it decomposes, What type of change will that be?
extreme tempature change is a chemical change
It's a chemical reaction, 'cuz heating and decomposing is.
i hope i past this test XC (july 3 2018
How’s rust a chemical change if wd40 gets rid of it
WHere is the worksheet???
