What generally happens to the kinetic energy and movement of liquid molecules as temperature is increased?

As temperature increases, the kinetic energy of liquid molecules also increases. This rise in kinetic energy results in molecules moving faster and with more erratic motion. As the temperature increases, the energy allows the molecules to overcome some of the intermolecular forces holding them together, leading to increased movement. This enhanced activity contributes to changes in properties such as viscosity, where the liquid may flow more easily as molecules are in constant, more vigorous motion. Therefore, the correct understanding emphasizes that the movement of molecules not only speeds up but also becomes less predictable with an increase in temperature.
