For my universe I am designing a spell that transports material from one item O to another A, for example for repairs. I envision it as taking material uniformly from the Volume of O.
Now, the question is: what is the minimal energy required? I am thinking, we could find the energy needed to free one atom from the lattice (or other atom configuration) of O. Then multiply by the Avogadro constant to find an estimate for one mol. Then transform to grams.
But how much is the energy needed for removal from the lattice? Is it the energy needed to make the desired fraction of O boil? Or could it be significantly less, if I am not rendering most of the atoms of O weakly bound (as in boiling)?
Obviously, the value depends on material. I want to know how and starting from what (table,…) I should compute the estimate.
