Answer

Brief Explanations:

The average kinetic energy of molecules is directly related to temperature. When the temperature of liquid - water decreases from 50°C to 30°C, the molecules have less thermal energy. As a result, they move more slowly and their average kinetic energy decreases.

Answer:

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