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.
Water density. Water density changes with temperature and salinity. Density is measured as mass (g) per unit of volume (cmÂ³). Water is densest at 3.98Â°C and is least dense at 0Â°C (freezing point).ater density. Water density changes with temperature and salinity. Density is measured as mass (g) per unit of volume (cmÂ³).
