Malnutrition can affect every system in the body, depending upon the cause of the malnutrition. In mild to moderate cases of malnutrition, no symptoms or signs may be evident; however, as the condition persists, the signs and symptoms will become more pronounced.
1 The mass and size of the molecules in a liquid and how closely they are packed together determine the density of the liquid. 2  Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume; D = m/v.  The density of water is 1 gram per cubic centimeter.
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.he density of a material is defined as its mass per unit volume.
