In the context of a temperature decrease from 50°C to 30°C in liquid water, the molecules move more slowly and their average kinetic energy decreases.
When the temperature of a sample of liquid water decreases from 50°C to 30°C, the molecules move more slowly and their average kinetic energy decreases. In this scenario, the cooling of the water causes a reduction in the average kinetic energy of the water molecules. As a result, the temperature decreases, and the molecules move more sluggishly.
