The kinetic energy is the lowest at the solid state.

Explanation:

The kinetic energy (#K.E.#) is given by: #K.E.=3/2RT#.

Where, #R=8.3145J/(mol*K)# is the universal gas constant, and #T# is the temperature.

As could be seen from the expression of #K.E.#, since for the same matter, solid state exists at a lower temperature than liquid state and than gaseous state, therefore, the kinetic energy is the lowest at the solid state .
