![]() ĭensity of crude oil, Density of fuel oils, Density of lubricating oil and Density of jet fuel as function of temperature.Īs 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. įor other substances, see density and specific weight of acetone, air, ammonia, argon, benzene, butane, carbon dioxide, carbon monoxide, ethane, ethanol, ethylene, helium, hydrogen, methane, methanol, nitrogen, oxygen, pentane, propane and toluene. In everyday life, it is often assumed to approximate the water density to 1000 k g. in the so-called normal conditions), the water density is equal to 1000 k g / m 3 kg/m3 k g / m 3. Both below and above this temperature, the density of water is lower. The density of distilled water is the same. At room temperature, water remains in a liquid state. The density of water at 25 degrees Celsius is 997 kg/m3. At room temperature ( 200C), its value is 998.2 kg/m3. The density of water is defined similarly to other substances.

The density of water reaches its maximum around 4☌. Density Standard Pure Water, density: 0.9982 g/mL at 20° C, density: 0.9970 g/mL at 25° C. The Density of Water At Room Temperature. See Water and Heavy Water for thermodynamic properties at standard condtions. The density of water depends on temperature and pressure as shown below: Note! Temperature must be within the ranges 0-370 ☌, 32-700 ☏, 273-645 K and 492-1160 °R to get valid values. The output density is given as g/cm 3, kg/m 3, lb/ft 3, lb/gal(US liq) and sl/ft 3. The calculator below can be used to calculate the liquid water density at given temperatures. ![]() See more about the difference between mass and weight Online Water density Calculator Freezing water expands over 9 by volume and ice floats on water because it is lighter. At 4 degrees Celsius pure water has a density of 1g/mL or 1kg/L and a specific gravity of 1. The density of water varies according to temperature and the degree of purity. Γ = 1.940 * 32.174 = 1.940 /(*) * 32.174 = 62.4 Density of pure water is a constant at a certain temperature not depending on sample. The density of water is 1.940 sl/ft 3at 39 ☏ (4 ☌), and the specific weight in Imperial units is The data presented in this database are divided. For version 2, in addition to density data it was decided to also present data on specific gravity and to define the terms used. ![]() In the Imperial system the mass unit is the slug, and is derived from the pound-force by defining it as the mass that will accelerate at 1 foot per square second when a 1 pound-force acts upon it :ġ = 1 * 1 and 1 = 1 /1 Version 1.0 included density data for 214 food entries in 16 food groups from six sources and version 2.0 includes 638 foods entries in 20 food groups from 11 sources. In the SI system, specific weight of water at 4☌ will be: G = acceleration due to gravity, units typically and value on Earth usually given as 9.80665 m/s 2or 32.17405 ft/s 2 Density is the ratio of the mass of an object to its volume. Specific weight is the ratio of the weight to the volume of a substance: Pure water has its highest density 1000 kg/m 3 or 1.940 slug/ft 3 at temperature 4☌ (=39.2☏). ![]() Hint: The formula of density is $mL$.Density is the ratio of the mass to the volume of a substance: ![]()
