What’s the difference between a physical change and a chemical change? What are elements, compounds, pure substances, and mixtures? So many definitions to learn! Don’t worry, Professor Dave will take you through the details.

Very Informative!!
Excellent class loved it 🥰!!
Professor dave your name is not like your Taught.
He just explained to me in 4 minutes what my teacher couldn’t in 40
eh i didnt even know what heterogenous or homogenous was but he did teach the others like element mixture and compound very well 🙂
how can scientists identify an element without a periodic table?
💞❤️Thanks sir ur all lecture's are very nifty 💞❤️ .
Sir I am class 11 student and I have opted (Physics chemistry and biology )
Do recommend me any best channel for physics' and biology .
Dude looking like Jesus

is water wet professor dave?
Hello from Georgia connections academy!
Why is Ranbir Kapoor teaching chem ?
Can anybody tell me why water is a pure substance? We use electrolysis to seperate the elements in water, and I'm assuming that's a Physical process like boiling, I wouldn't think adding electricity is any more chemical than adding heat to boil. If that was true then water wouldn't be a pure substance, so what am I missing? I really appreciate any response, even guesses, but please tell me if you aren't sure of your answer so I can act accordingly.
JESUS SAVED ME! 😭♥️
I speak for the tees

You should have added a timer for the exercise so that I know if I need to pause.
What do u mean by solids and liquids having fixed volume, how about thermal expansion
Hi BSCE-1A
Are you the Jesus of science
thank you lord !
I hope there's an alternate universe where every teacher explains like you. Thank you btw
i owe you my entire life. i’m in ap everything at a college level as a sophomore & i can’t get past basic science. bless you, sir. bless you.
