10:29 sir i know u simplify a really complex topic but if entropy is amount of useless energy then an increase in temperature would decrease the amount of useless energy ?
Hi, thanks for your detailed explanation! But the one question is still unanswered: how do scientists measure entropy empiricaly? Like how do they form standard entropy charts for different compounds? Maybe it was not mentioned because it is very complicated for students to understand, but nevertheless, I want to know more)
That's a great question! Standard entropies can indeed be measured experimentally using calorimetric techniques. This involves determining the heat capacities of substances over a range of temperatures and accounting for phase transitions. When calorimetric data isn't available or can't be obtained, we can also calculate entropy values theoretically by considering the number of microstates accessible to the particles in the system (using the formula S=kln(Ω)). This approach uses knowledge of the molecular structure and arrangement of particles in the substance to estimate entropy. Hope that helps :)

Thank you so much! This was one of the best explanations for this confusing topic
Thank you! Glad you found it helpful :)

thank you so much ! i cant believe that i had understood this completely wrong !
Thank you! Glad it helped :)
Sir which textbook did u use , am doing ib so want to do my essay on this topic but most ib chem book do not go in depth as u explained in part 2
I didn’t use a textbook, sorry! Just my understanding from years of studying and teaching
