How does the kinetic-molecular theory explain
the following properties of liquids: (a) relatively
high density, (b) ability to diffuse, and (c) ability
to evaporate?
(3 Points)

a. a result of the close arrangement of liquid particles

b. just like gases, the constant and random motion of particles in liquids causes diffusion. it is slower than in gases porque liquid particles are closer together

c. occurs because the particles of a liquid have different kinetic energies, particles with higher than average energies move faster

Explanation:

I know

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
