D)are attracted to each other by strong forces.
E)occasionally come to rest.

Question

According to the kinetic molecular theory of gas behavior, gas molecules are assumed to move rapidly in random directions. This is what gives them their high kinetic energy and allows them to fill their container. The theory also assumes that gas molecules are far apart relative to their own size, so option A is incorrect. Option B is also incorrect since the kinetic energy of a molecule is proportional to its temperature, not equal to it. Option D is incorrect since the theory assumes that gas molecules do not attract each other strongly and are essentially independent of each other. Option E is also incorrect since gas molecules are assumed to be in constant motion, never coming to a complete rest.
