Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor.
The statement that correctly describes the nucleus of the atom is that most of the mass of an atom is located in the nucleus. The nucleus contains neutrons and protons. Rutherford reasoned that all of the atom's positively charged particles were contained in the nucleus and the negatively charged particles were scattered outside the nucleus. Both neutrons and protons are given a mass of one atomic mass unit or amu. Electrons have a mass many times smaller than 1 amu.
