    A decrease in temperature indicates decreased kinetic energy of the molecules.

    KE ∝ T, so a decrease in temperature means a decrease in kinetic energy.

    Decreased kinetic energy of the molecules.

    Explanation:

    The kinetic energy is the energy of movement.

    The energy is associated with the speed of a molecule.

    If we increase the temperature the speed of a molecule increases, increasing the kinetic energy of the molecule.

    Thus

    Kinetic energy is directly proportional to the temperature.

    So if we decrease the temperature it will decrease the kinetic energy of the molecules.
