Heavy water is indeed heavier than normal water (which contains a tiny amount of heavy water molecules naturally), and heavy-water ice will sink in normal water. As shown in the figures, the change in density is not linear with temperature - this means that the volumetric expansion coefficient for water is not constant over the temperature range.Water density, specific weight and thermal expansion coefficient at temperatures given in degree Celcius: For full table with Specific Weight and Thermal Expansion Coefficient - rotate the screen!

Is often assumed to approximate the water. number of moles of water in one liter. Freezing water expands over 9% by volume and ice floats on water because it is lighter. Example: to find the density of water at 16.1 C, you would first find the whole degree by searching down the left hand column until you reach '16'.Then you would slide across that row until you reach the column labeled '0.1'. Substances can change their density depending on temperature and pressure. Pure Water Divide by 10 3 to get the density ing/mL. The salilinty changes the specific gravity far more than the temperature WARNING! calculator, Metres The range of temperature that is there in an indoor science lab (10 C - 21 C) mostly accounts for the density of the water to stay in and around 1 g/cm3.
