Entropy and Enthalpy concepts with easy to understand examples. More about Entropy and how it changes in chemical reactions here: • Understanding Entropy ... Subscribe! www.youtube.co...
the last 2 or 3 minutes makes sense, since you used a familiar chemical reaction we can visualize, such as the "boom" and flame when water is formed, we know our system lost heat from that, as well as the fact the water molecules move less than the gasses did, so enthalpy was reduced because the system lost heat. That last part belongs at the beginning? I think so. When you light gunpowder you get heat, noise, etc as well as smoke, dust, etc. But if you gathered up the remains, you only have more powder, so you must know about the energy release or probably wouldn't easily find out you lost energy like you did when comparing gases to liquid with the water experiment.
Delta H is final Enthalpy minus the Initial Enthalpy. If Final Enthalpy is higher then energy went into the system. And, H2-H1>0 or positive. If Final Enthalpy is lower than the initial Enthalpy then the energy went out of the system. And, H2-H1
What sometimes was difficult at least for me to figure out is the fact that, liquids just like the great given example on the explanation have more energy than solids, once their molecules vibrates more (considering of course, the same substance/material), thus the exothermic reaction regarding "Solid to liquid transformation"is related to the atomic bonds destruction.
I can't believe I just watch this comment, you are very funny. Yes, my son brings lots of entropy to the universe, you should see his play area. I hope you found the video helpful.
Please make more videos! This video was extremely easy to understand, and I was able to get everything watching it once :D.
Thank you for your kind words
I like the visualizations, and the short word comparisons... randomness, disorder, chaos. Very helpful. Thank you for putting together this video.
Thank you Nestor. It's been 30 years since I studied Thermodynamics and am tutoring a 10th grader. I needed this refresher. -Paul

Very well explained., now feel ready for my tekst.
👍🏻
Really like your accent and easy to follow explanation! Great video!
god it took me so long to figure out what this means but i love your analogies ! it really helped me figure it out :)
Glad it helped!
Thanks a lot !! You're presentation is fantastic !!Finally gott those basocs cleared!! You made my day !! :)
I love your accent ! it made the video sound pleasing

Finally! Someone who helped make sense of this matter
👍🏻
Only video that made sense to me. Thank you
👍🏻
Really Very Helpful
I will always Be Thankful to you👏🏻👏🏻
👍🏻
Indians always clear things up
🤔
Oh yes just what I needed Chem final tmrw 😬

This video helped me a lot to understand entropy.
Great explenation! Thank you so much
Great explanation in very simple sentences...
thanks for this video. It was super helpful!
You're so welcome!
this is very helpful thank you!
great video!
Glad you enjoyed it
very helpful video but please try not to overwrite next time!
Thank you for your suggestion... It's good to learn what needs to be improved :)
Thannk you so much! Love the explanation
i new to the subject and after a long struggle i able to clear through your class......thank u master........
7:35 - ice melting into water absorbs energy (heat) or releases? The latter is counter-intuitive !
👍🏻
Do these terms belong either only to chemistry or to physics or rather to both of them sciences?
These terms are more commonly seen in chemistry but physics deals with energy as well, besides, both subjects study matter and energy.
These terms are pertinent to both, chemistry and physics.
i like that, nice idea
Thank you very much
Nicely done
love that background crying noise😂
I am glad you liked it... totally unintended :)
good job
Somehow I could undestand your doodling. Thanks
👍🏻
thanks dude
thanx
👍🏻
bless you.
thank you!!!!
👍🏻
@@caffeinatedteacher hahaha it’s been four years, friend. I’m almost done with my masters now !!!
GOD BLESS YOUUUUUU
great vid
Thanks man... I've thinking about making another thermodynamics video.
The kid in the background has more Entropy.
I can't believe I just watch this comment, you are very funny. Yes, my son brings lots of entropy to the universe, you should see his play area. I hope you found the video helpful.
Good but somethings It is hard to understand his accent
Amazing explanation (Y)
Nice explanation, but you should erase the board first before goin to another explanations.
Hi Ric, thank you for your comment. My recent videos have a nicer flow and look cleaner.
Really .......
Excellent
Great explanation, thanks a lot. But please don't overwrite!!!
👍🏻
Thanx
