You know you just can't review this topic enough. I had Gen Chem over a year ago, and I'm already starting to forget all this jazz. Thanks for the quick refresher - and slightly new perspective on the subject. Very assimilable.
thank you very much sir as a Chemistry student from today onwards i will always see ur videos its really fruitfull for the advancement of chemistry in the world thank u sir
The products have more energy because energy has been absorbed into the products usually in the formation of bonds. When energy is added to a system it is endothermic.
I get confused with enthalpy and heat. So heat is just the transfer and enthalpy is the change of energy of the system at a constant pressure?, sort of like "standard enthalpy"?
In endothermic reactions, reactants get to absorb energy right? It is the reactants that get to have the formation of bonds or combinations. I really don't get it. How come an endothermic reaction will have more energy in its products
Can anyone plss solve this A sample of argon gas at 1 atm pressure and 27 degree C expands reversibly and adiabatically from 1.25 dm^3 to 2.5 dm^3. Calculate the enthalpy change in the process.Given that Cv for Ar is 12.45J/k/mol and antilog of 0.199=1.58
this is thermodynamics in chemistry. when we study this in chemistry we always consider ourselves to be in the system. N then when we do some work we reduce our energy. For example If you have 40kj of energy internally and workout consuming 20kj . Remaining energy is 20kj . Thus work done is -20kj. when you study physics you stay in the surrounding then work done by system is accepted by the surrounding and thus positive.
Mr. Causey...honestly you are a lifesaver. My chemistry teacher literally doesn't teach and you help so much! Thank you!
I'm gonna make a playlist of this and play them all night while I sleep.
You're save me. I can't found Chemical Thermodynamics in Brazilian Portuguese, but I found this video. I learned a lot with you. Thank you.
Ma Argilero Thank you for watching and commenting.
This video really helped me understand thermodynamics clearly and without any misinformation.
Thanks for commenting!

I love your videos, they help me soo much. love them :)
Thank you for watching and commenting.
The content is very well organized.
Marea Spentzos Thank you for watching the video.
Entropy has yet to diminish its order.
Great, you are a lifesaver
Thank you for watching and commenting!
Awesome stuff. Saw it before exams. Thanks Mr Causey ☺☺
You're welcome! Thank you so much for watching.
It's a superb lecture, guest what you are a genius!!!
you explained and help me tounderstand easily.thank you sir
Great Video! Like always, you rock!

thank you Mr. Causey. Very helpful
You're welcome. Thank you so much for taking the time to comment. It is greatly appreciated.

thanxx aloootttt....u made me understand the topic...
This helped me a lot, thx!!!
Great video, very helpful.
Very concise , Love it!
Thank you.
Dude nice i cant belive y so less views ur vid was great ty :D
your video was really good man!
Thank you.
THANK YOU FOR THIS!
You're welcome.
video rated I for intelligence. you sir just got a like
Thank you! I see you have a sense of humor.
u r the best...thanks so much..u have helped me a lot :)
You're welcome. Thank you for the kind feedback.
Good video Thank u
Thank you.
Thanks for this vids. :)
Great vid

This is amazing
Because reactants absorb energy in an endothermic reaction the products now have that energy stored.
Thank you!
You're welcome! Thank you so much for watching.
Studies have shown that it increases your IQ!

Can anyone plss solve this
A sample of argon gas at 1 atm pressure and 27 degree C expands reversibly and adiabatically from 1.25 dm^3 to 2.5 dm^3. Calculate the enthalpy change in the process.Given that Cv for Ar is 12.45J/k/mol and antilog of 0.199=1.58
the best
Thank you so much!
Enthalpy is the heat content.
why is it that when the prodcucts have more energy its endothermic
Since worked done by the system is positive so why you have put negative sign.
this is thermodynamics in chemistry. when we study this in chemistry we always consider ourselves to be in the system. N then when we do some work we reduce our energy. For example If you have 40kj of energy internally and workout consuming 20kj . Remaining energy is 20kj . Thus work done is -20kj.

Good keep iTunes
excellent easy to understand but its not much depth
Rohith kumar It's just an intro. Thanks for watching and commenting
+Mr. Causey it's excellent but please make an other video for higher level in the same way
I loved it... until it gets to entropy and then comes all the exoteric explanation of order in the universe bla, bla, bla,.
Entropy is a rabbit hole. In fact he doesn't get it quite right in this video.
