What is the best explanation of the kinetic molecular theory as it relates to the energy of the molecules in the states of matter?
A. The molecules in a gas have greater kinetic energy than those in a liquid, which in turn have greater kinetic energy than the molecules in a solid.
B. Kinetic energy cannot be created nor destroyed, and, as a result, all states of matter have the same kinetic energy.
C. The molecules in a gas have greater kinetic energy; therefore, they are more tightly packed than the molecules in either a liquid or a solid.
D. The molecules in gases and liquids, in constant motion, have greater kinetic energy than those in a solid, which do not move or vibrate because their position is fixed.
