Does the gravitational potential energy affect the burning of two logs?

[QUOTE="prodi, post: 6047772, member: 649824"] [h2]Homework Statement [/h2] Let's consider two wooden logs. We burn the first one at the base of the mountain and the second one on the peak. Which one is releasing more energy? Do they release the same amount of energy? Does the potential energy affect the burning [h2]Homework Equations[/h2] ## \Delta H =## Sum of bond energies broken - Sum of bond energies formed ## E=mc^2## ## Potential \ Energy = mgh ## ##v_T=\sqrt{\frac{3kT}{\mu m_H}} ## [h2]The Attempt at a Solution[/h2] I know that the reaction enthalpy depends on temperature so they must release different amounts of energy. So I guess the answer will be the log located on the peak of the mountain. Another approach I tried is to apply the Einstein equation, ##E=mc^2##. Supposing that the two logs have the same mass the answer will be simple: both release the same amount of energy. Also I was thinking about the oxygen levels for this two altitudes. The log at the lower altitude has more oxygen so it should release more energy. But if the two logs have equal masses, the oxygen level should not matter. Am I wrong? [/QUOTE]
