Which is true with respect to the kinetic energy of a molecule?

This question includes four answer choices: A) it is the lowest at low temperature B) it increases at low temperature C) it is the same at all temperature D) is it the lowest at high temperature The right statement is the option A) it is the lowest at low temperature. The Molecular Kinetic Theory describes the behavior of the gases in terms of the motion of the particles. It makes several assumptions about the size, the motion and the kinetic energy of the particles (molecules). Given that the kinetic energy, KE, is KE = m * v^2 / 2 and that the speed of the particles is higher at higher temperatures and lower to lower temperatures, you conclude the the kinetic energy of a molecule is the lowest at low temperature, i.e the option A).
