Which of these statements are consistent with kinetic-molecular theory? Select all that apply.

a. The molecules in water at 100°C have more kinetic energy than the molecules in water at 0°C.

b. As a solid is heated, its particles absorb thermal energy and move more slowly.

c. The carbon atoms in a diamond vibrate back and forth in place.

d. The particles of matter in the sun are in constant random motion.

e. If you superheat a gas, its particles eventually stop moving completely.

Emerson Griffith · Answer 1

The Kinetic Molecular Theory focuses on the average kinetic energy of the molecules with respect to temperature. As the absolute temperature increases, the kinetic energy also increases. Same is true for the opposite situation. The kinetic energy is manifested by rapid collisions. Thus, the answers are A, C and D.
