To learn about a fourth phase of matter, plasma, which is what's inside stars, check out my astronomy tutorials!
what about plasma?
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 .

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! 😭♥️

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
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.
thank you jesus
Let's have a moment of honesty. We learn way more and understand mare more better on YouTube than 2 hours classes
