It's used to calculate almost everything , you just have to put in the values .
Quote from: Thebox on 31/03/2019 18:11:09It's used to calculate almost everything , you just have to put in the values . So what values would I need to supply in order for the equation to show me the amount of energy released when hydrogen burns in oxygen?
because that would be the value of u would be the value of hydrogens u .

Internal energy ,
Quote from: Thebox on 31/03/2019 18:24:32Internal energy , I presume that V means volume and t means temperature. Are all of these in standard metric units? Where do the values for oxygen come in?
But that is more deep discussion than my simplified process equation .

What does the u mean?Internal energy , Do you mean this?https://en.wikipedia.org/wiki/Internal_energyOr do you mean something made up?
So, you are looking for the internal energy for oxygen?
I meant, as part of your demonstration that you are not talking nonsense, by calculating the heat of combustion of hydrogen, you would need to know the internal energy of oxygen.I'm guessing you need the same parameter for hydrogen.Anything else?You aren't going to suddenly decide that you need the rate of change of density of jupiter's 23rd biggest satellite or something like that?
OK, here's a question somebody already asked.How much heat is released by the combustion of hydrogen?What inputs do you need?
I mean ask a question , how big is an atom ?
Are you talking about the energy released when an hydrogen atom is split or the heat energy that is generated by kinetics between the friction of particles ?
Quote from: Thebox on 31/03/2019 21:41:13I mean ask a question , how big is an atom ? That's another example of something that we can check against known data. Tell me what each one of those variables in the equation means so that I can do the calculation.Quote from: Thebox on 31/03/2019 22:07:45Are you talking about the energy released when an hydrogen atom is split or the heat energy that is generated by kinetics between the friction of particles ? Neither. Combustion involves the breaking of the bonds in the H2 and O2 molecules and the formation of bonds in H2O.
I think (u) may be the mass in your question and V would be the occupied volume of space

I mean ask a question , how big is an atom ? V==4/3 π r³ / tWhat's exothermic process ?x=Why do gases expand when heated ? >V = It has so many uses , quite magical .
