    The molecules move more slowly and their average kinetic energy decreases.

    Step-by-step explanation:

    The temperature of a sample of liquid water changes from 50°C to 30°C.

    We know that as the temperature decreases the molecules of a substance decreases and the average kinetic energy also decrease.

    So, the molecules move more slowly and their average kinetic energy decreases. (Answer)
