What effect does the temperature have on the kinetic energy of molecules?

The relationship between temperature and the kinetic energy of molecules is fundamental in the study of thermodynamics. As temperature increases, molecules gain more energy, causing them to move more rapidly. This increase in movement represents an increase in kinetic energy. The kinetic theory of gases states that the temperature of a substance is directly proportional to the average kinetic energy of its molecules. Therefore, when temperature rises, the kinetic energy of the molecules also rises, reflecting more vigorous movement and interactions. This principle applies to all states of matter, confirming that the average kinetic energy of molecules indeed increases with temperature.
