After passing the university entry exam thanks to your videos, I am now studying Electrotechnical Engineering in the first semester. Your videos are still my most frequently used ressource when I fail to understand anything in the lectures. Thank you for your great work!
Enthalpy = Internal Energy + pV = U + pV where p = pressure and V = Volume Change in enthalpy = change in internal energy + p x change in volume. As you assumed, the volume remains constant here.

Thank you for the explanation, very easy to understand and follow 🙏
Glad it was helpful!
why is heat release equal to enthalpy change ? since volume is constant? thanks in advance 😊

is the amount of heat gained by the water and calorimeter the same?
In reality the calorimeter will also absorb some of the heat, but for simplicity we ignore that or we roll it up into a single heat sink.
Thank you.
You're welcome!
