Question

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.

Answer 1

The answer is : A
