Hey Sal in the exothermic and exergonic reacction where did the purple/pink atom go in the two pair of atoms molucule and in the endothermic and exergonic reaction could you colour/color every atom diferent. Sal I also signed n on khan academy because of your great teaching. Bye Sal
I though freezing water is a spontaneous reaction its exothermic and has decreasing entropy. Shouldnt it be exogonic vs endogornic? Or does this only apply to constant temperature and pressure?
Sorry that no one replied, but in freezing a liquid into a solid, heat is released because the potential energy of the attractive forces between molecules is converted to heat. Since a solid is intrinsically more ordered than a liquid, freezing decreases disorder and entropy of the system decreases (ΔS
The way you repeat your term you JUST said, literally makes me so confused... "constant pressure... constant pressure, you can define endothermic....endothermic.."
Cleared my concept immediately, ur da best Khan
Very good explanation, Thank you
Ur teaching style is awsome✌
thanks learned it and understood it nicely and got an A* in my Exam

I have beenfollowing your explanations khan you are a genuis you make me understand
Loveittt.....
Nice
If breaking bonds requires energy then why is increasing enthropy exergonic?
Is this considered high school or university level science?

Could you explain it in English?
Anusha and Neshat right!
Not his fault youre a brainlet

I just skip whenever this dude starts repeating
Look I love Khan its helped so much, but cannot stand it when he repeats himself constantly, its like nails on a chalkboard
Sal Khan or Khan Academy in "Look I love *Khan* its helped..."
Does this guy repeat every word in every video? “Work” “work” “release” “release” I don’t think I can handle that
I just posted a comment and scrolled down and saw yours! You said it. =)
watch your mouth kid
