liquid is defined as fluid matter having no fixed shape but a fixed volume; it is one of the three states of matter. A liquid has the ability to flow as well as take the shape of a container. At the same time, it resists compression and maintains a fairly constant density. Given that temperature directly affects the kinetic energy of molecules in a liquid, the effects of temperature on liquids can be described in terms of kinetic-molecular theory.
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.
