Well, all of this we owe it to Bohr who analyzed the atomic emission spectrum of hydrogen and he could probe matematically that it was a result of movement of e- from an especific energy level to a lower one. The understanding of levels of energy took to the development of the atomic theory
In order to calculate the amount of heat energy required to melt 347 grams of ice, we need to will apply the equation:
Q
= ml, where m is the mass of substance and l is its latent heat of fusion. For ice, the latent heat of fusion is 334 joules per gram.
Therefore:
Q = 347 x 334
Q = 112,558 joules of energy
