23:45 I think this was a mistake; the 1000 grams of water could have more total energy, and it would take more heat to raise the temperature, but since heat is a process function I don't think the water can possess heat
I believe 273 is used for gas law calculations where STP condition is assumed vs. 298 is used for standard state thermodynamic calculations. Someone correct me if I am wrong.
ya so breaking a bond requires energy input? Because bond enthalpy is usually given as Energy required to break a bond (so it is +). then when forming a bond you flip the sign to negative (-) meaning formation releases energy. "Breaking a bond requires energy and is always an endothermic process (H >0)"
thank you for the concise clear explanation!
Hello! Is there any way I can access the gen. chem notes? i only see gen bio, orgo, and biochem. Keep up the good work!
hey the notes are up by now if you need them still. But at the point you asked he had not uploaded them.

Yusuf I just wanted to say I love your videos so much. Inshallah your content will help me get a 520+.
isnt STP for temperature 273 K not 298? or were you just using 25 C at Kelvin as an example?

25 c is the temp at stp, converted to kelvin its 298. 273 is just the conversion addend
@@nassimamro485 STP in chemistry as well as the MCAT is 0 C
Great video! @37:16, did you mean to say Bonds forming= Releasing Energy and Bonds breaking= Absorbing Energy and not the other way around?
