Properties of Matter:

Energy is the ability to move change or change matter. If energy is released during a chemical reaction it is an exothermic reaction and the products have less energy than the reactants. If energy is absorbed during a chemical reaction it is an endothermic reaction and the products have more energy than the reactants.

Enthalpy is the measure of the energy content.
Entropy is the increasing of disorder.

Mr. Causey...honestly you are a lifesaver. My chemistry teacher literally doesn't teach and you help so much! Thank you!

[ursaminor]

I'm gonna make a playlist of this and play them all night while I sleep. 

[BASI]

This video really helped me understand thermodynamics clearly and without any misinformation.

[MaArgileroart]

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.

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.

[kiransapkotamyagdi]

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

[DaftWullieFeegle]

I love your videos, they help me soo much. love them :)

[laminsaidy]

It's a superb lecture, guest what you are a genius!!!

[amanaayush]

Awesome stuff. Saw it before exams. Thanks Mr Causey ☺☺

[subramanyamhn]

you explained and help me tounderstand easily.thank you sir

[kchixazan]

thanxx aloootttt....u made me understand the topic...

[mrcausey]

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.

Dude nice i cant belive y so less views ur vid was great ty :D

[besttimesoflife]

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

[RommyRenteros]

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"?

[reecezandbergen]

video rated I for intelligence. you sir just got a like

[yazeedalamri]

u r the best...thanks so much..u have helped me a lot :)
 

[mrcausey]

Because reactants absorb energy in an endothermic reaction the products now have that energy stored.

[Lakshya_Bevli]

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
