Heat
An increase in the temperature of a liquid causes an increase in the average speed of its molecules. As the temperature of a liquid increases, the molecules move faster thereby increasing the liquid's kinetic energy. Furthermore, the higher the temperature of the liquid, the lower the viscosity since an increase in kinetic energy reduces the forces of intermolecular attraction. Viscosity is the quantity that describes a fluid's resistance to flow. Since kinetic energy is directly proportional to temperature, a liquid that is heated sufficiently forms a gas. This property can be shown in experiments by heating liquids. A Bunsen burner is one of the most commonly used methods of heating liquids in science labs.
Cold
As the temperature of a liquid falls, the speed of its molecules slows down. Since the molecular speed slows down, the kinetic energy reduces as well, thereby increasing intermolecular attraction of the liquid. This attraction in turn makes the fluid more viscous because viscosity is inversely proportional to the temperature of a fluid. Therefore, if a liquid is cooled sufficiently, it will likely crystallize, changing to its solid form. This property can be shown in a simple experiment involving a freezer and different types of liquids
