Answer:
Nonpolar molecules
Explanation:
Nonpolar molecules are those molecules that are produced by the union between atoms that have equal electronegativity, so the forces with which the atoms that make up the molecule attract the electrons of the bond are equal, thus causing the cancellation of these forces. An example of an nonpolar molecule is the Oxygen (O2) molecule. In this molecule each oxygen atom attracts the electrons shared towards itself with the same intensity but in opposite directions, therefore the forces of attraction are annulled and the molecule does not become a dipole.
b. False
The correct statement is: An atomic nucleus contains most of the atom’s mass.
All of the atom's neutrons and protons are in the nucleus, and the atom's electrons are outside the nucleus.
It would take more than 1,800 electrons to add up to the mass of one neutron or one proton.
But no atom has more than around 240 electrons, so we can see that almost all of the atom's mass is in the nucleus.
The atomic nucleus is best described as containing most of the atom's mass due to the presence of protons and neutrons, not as being negatively charged or mostly empty space.
The correct statement that describes an atomic nucleus is that an atomic nucleus contains most of the atom’s mass. This is due to the presence of protons and neutrons in the nucleus which carry nearly all the mass of the atom. The nucleus is not negatively charged, it carries a positive electric charge because of the protons. It is also not correct to say that it's mostly empty space as this describes the whole atom's structure where most of the space is taken up by electrons circling the nucleus.

Answer:
1. Evaporation: The water evaporates from the water bodies like seas and oceans.
Transpiration: The water evaporates from the plant's leaves.
2. Condensation: The evaporated water condenses to liquid droplets which to form clouds.
3. precipitation: When the cloud becomes heavy, water rains down. This is known as precipitation.
The water rains down in rivers and seas and oceans. From rivers, it runs off back into the seas.
