In general, the liquids tend to expand when their temperature increases. For example, the same mass of boiling water occupies more volume at 100 degrees Celsius than at 20 degrees Celsius. Therefore, increasing temperature decreases density.
The density of a material is defined as its mass per unit volume. The density of liquid water is normally given as 1000 kg/m3 or 1 g/cm3 as a very accurate estimate, but often ranges slightly below this value, depending on temperature. Unlike other agents that tend to freezing point, water tends to expand as at freezes; it therefore becomes less dense.
