  1. 💞❤️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 .

  2. 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.
