(B) (I) If John took five ice cubes from the freezer and place them into a cup after 5 minutes, he returned and saw water this process is called melting.

(ii) if he put the same cup into the freezer and turned into ice in 5 minutes this

process is called freezing.

(iii) if John places the ice from the cup into a pot on a lit stove for 2 minutes and leaves, and he returned and find the pot empty this process is called evaporation.

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
