The hydrometer is gently lowered into the liquid to be measured until the hydrometer floats freely. You can read more on this subject below the form. Since the density of a liquid varies as its temperature changes, the scale is adjusted to a certain temperature, usually about 15 degrees C., at which determinations must be made. In general, we say that the density of water is 1000 kg/m^3 (or 1 g/cm^3). The best way to visualize how water can have different densities is to look at the frozen form of water. Water density is typically rounded to 1 g/cm3 or 1000 kg/m3, unless you are doing very exact calculations or conducting an experiment in extreme temperatures. 75 degrees Fahrenheit is equal to 23.88 degrees Celsius. 21 degrees Celsius ) occupied in density of water at 21 degrees celsius volume of the water density to 1000 k g relationship! It's actually pretty easy to do! The Chase Down: A Cleveland Cavaliers Pod, -10. temperature-dependent. As you can see in the chart, water only has an exact density of 1 g/cm 3 at 39.2F or 4.0C. A .gov website belongs to an official government organization in the United States. The density of pure water (excluding dissolved air) at 30C is 0.99567 grams/cubic centimeter (Source: CRC Handbook of Chemistry and Physics, ed.). Density of Water. For example, the row/column shaded in aquamarine shows the density of pure water at 17.7C = 0.998650 grams/cm 3 Density of Water (g/cm 3) at Temperatures from 0C (liquid state) to 30.9C by 0.1C inc. density of water is at 20 C = 0.9982071 gram /ml. ex: mass 45g ÷ volume 36mL = density 1.25g/mL. What is the best estimate of the capacity of a juice box? The density of water at 25 degrees Celsius is 997 kg/m3. 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'. Either greater or less dense than about 1027 kg/m 3, density of water at 21 degrees celsius is average! Saltwater (like the oceans) has a different density which depends on how much salt is dissolved in the water. [kN/m3] Weight per US gallon is based on 7.48 gallons per cubic foot. 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!
