The intermolecular forces for Iodine are much lower than the energy needed to free it from its crystal lattice. Once Iodine has enough energy to break out of the lattice, it also has enough energy to separate from its neighbors. And so, it sublimes.
The CNO cycle, the abbreviation for the carbon-nitrogen-oxygen cycle, is a catalytic cycle by which the stars produce helium from elemental hydrogen, via a series of nuclear fusion reactions.
This cycle involves the fusion of four protons with carbon (), nitrogen isotope (), and oxygen isotope (), to give an alpha particle and two electron neutrinos and positrons.
The reaction involves the regeneration of carbon () nucleus in the last step.
I would he would try to enter as the tide is rising, and leave as the tide is falling. Those things happen at all different times of day during a month. Hope it helps!!
