Physical and Chemical Changes

[@ahlamalzahawi5233]

I love your lecture. I took physic class and I watched your videos and now I am taking chemical class and I am still watching your fabulous videos... all love to you

[@adr2367]

Physical change : A physical change is a temporary in which no new substance is formed and the chemical composition of the original substance remains the same even tho some of its physical properties like colour state size etc. Might change. CHEMICAL CHANGE - Chemical change is a permanent change, in which new substances r formed whose chemical composition physical and chemical properties are different from those of the original substance .

Can i Just thank you ever so much because ever since my last two years of High school i have been watching your video's and they have assisted me so much and starting my first year of medicine i continue to follow and watch your video's you have helped me more than my teachers ever have and i am forever in your debt. Thanks again :)

Lots of Conflicting ideas re dissolving a substance like sugar in water out there. How do you rebut the argument that there's a taste change and that you can't seemingly reverse the process? Thoughts?

[@spicyshizz2850]

The chemical changes can be confusing with bullet points such as cloudy and temperature change. For cloudy I immediately thought of putting salt into a cup of water. For temperature change I thought of H20 going from ice to water to vapor. I just need more practice i guess.

[@MsAbdimalik]

thanks you have helped me pass class

[@famix0643]

but are there changes that can be both physical and chemical?

[@vanyajain8379]

famix06 no they can't take place at a same time but can be done in steps like chewing our food and digesting it

[@vanyajain8379]

Nguyễn Crystal I don't really know to be honest but water boiling is a phase change and phase changes are always physical reaction not chemical ones so the substances inside the soup will never change chemically

[@vanyajain8379]

Nguyễn Crystal I don't know....I am so sorry

[@flip1246]

I would think that cooking meat is both. When you cook meat there the brown on it is called the maillard effect (you wanna check the spelling on that) but that is when the proteeins on the surface break down and combine with the sugars present in the fats. And it is a physical change as you heat it up.

[@tamarasiblani]

my hw was to watch this and answer these questions: Physical change. 1.What is a physical change? 2.Give 5 examples 3.When water is boiling, what do the bubbles contain? 4.What do we get when we dissolve sugar in water? Chemical change 1.What is the first example of a chemical change mentioned in the video? 2.List some clues of a chemical change 3.Which clue we cannot rely on in the lab? Why? 4.What are the substances on the left side of a chemical equation called? 5.What are the substances on the right side of a chemical equation called? 6.What do we mean by a balanced chemical equation? 7.Do we change subscripts or coefficients in order to balance a chemical equation?

[@quintonwilson8565]

Balanced, as all things should be.

[@33Skygazer]

A cloud forming in the atmosphere is not a chemical change, but a physical change since the water vapor is condensing on condensation nuclei.

[@8block8_creat]

That's chemical changes because nature is doing that

[@33Skygazer]

The water is still water, thus a physical change.

[@joseluistorres37]

This video helped me a lot thanks !

[@hcstewart3040]

Awesomeness for upper elementary!

[@BogwoppitBruce]

It's a reversible, physical reaction. When the water evaporates you will be left with sugar crystals again. No chemical reaction has occurred. There will be no real taste change as the sugar and sugar water both taste sweet

[@Levantinelyjan]

if water boils, wouldnt it be a chemical changes ince it produces bubbles?

[@8block8_creat]

I'm not sure about that one

[@maryholmgren5874]

The water is producing bubbles due to a temperature change, not because a second chemical was added. The water is still water, just vapor.

[@futureself6126]

Mary Holmgren isnt temperature change mean that its a chemical change??

[@maryholmgren5874]

You are adding the heat. Chemical change evidence is when you have a temperature without adding heat. For example, if you combine two liquids and the temperature increases without you adding the heat, then you have evidence of a chemical change.

[@maryholmgren5874]

If you heat water in a beaker or pan over a Bunsen burner or on a stove, you are adding heat through the combustion on some hydrocarbon (methane or propane). Hotlightning

I thought color was a physical property? But a substance undergoing a change of color is a chemical change? Now I'm confused.

I'm watching this in chemistry right now.

[@rachelmcadamslover]

there is no taste change. Sugar tastes the same before you dissolve it in water and after you dissolve it. Still tastes like sugar. On the other hand, bread doesn't taste the same before you bake it and after you bake it and thus because taste change has occurred, therefore chemical change has also occurred.

[@Webzybird]

Thank you! really helpful!

Thanks a lot! You had just save me!!!

[@haydn4ever]

Thanks so much for this video. I'm an adult returning to school. I thought I had it all figured out after watching your video....but, I ran into another example in my reading assignment that was totally different from what I thought it should be....please help!! Why is a fried egg considered a chemical reaction? It's still an egg it just changes form! ugghh!! I'm so confused! I would've thought it would be physical. Is it the temperature change? But what about boiling water? The temperature changes with that too? :(

[@haydn4ever]

***** Thank you so much! Another thing that helped was realizing that a with a chemical change you can't get back to the original form. A fried egg will never again be as it was in the shell. Prior to cooking you could put it back in the shell in the same state. It took awhile, but I kept watching video after video til I understood. This video was great though!
