That is great, thank u again. :smile:

Does anybody know why the entalpy change for a reaction differs in different pressure and temperature?

Have you tried the Cambridge reading list? I think it is quite nice, bothe the 'readable maths' part and the 'history of maths' part. :smile:

I've got two questions here. Why is the enthalpy cahnge for a specific compound differs when temperature, pressure is different? Can we use the entropy change to deduse whether an reaction can happen naturally? Thank u

Sorry, it should be Higgs Field.

How does probability relate to that wave length is momentum over plank constant? :confused:

:wink: Thank god i finally find a physics forum. Does it give light the the equation E=mc^2 that if mass comes from Giggs field carried by Giggs Boson? Thank u :smile:

It is said that most mass in the universe consists of dark matters which don't emmit light. What is the difference between dark matters and planets? Thank u.
