Which of the following best describes the kinetic theory model? a. all particles in matter eventually stop moving

b. energy changes have no effect on the state of matter

c. when particles in matter gain or lose energy , they change state

d. no matter how much energy is present particles never move

Answer c: "when particles in matter gain or lose energy , they change state"

Explanation:

As energy is provided to the molecules of the substance in question, they acquire more speed or vibration, increasing their separation in the substance, which can become then a liquid , or a gas. The reverse path also happens as the particles give away energy.

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
