The Roman numerals indicate various ice phases. ‡ Ice XI triple point is theoretical and has never been obtained Phase diagram Log-lin pressure–temperature phase diagram of water. Table of various forms of ice Properties of various forms of ice Find out the exact value of water density at 4☌ (40☏) and see a photo gallery of water properties. Melting point of ice at various pressures ĭata obtained from CRC Handbook of Chemistry and Physics 44th ed., p. 2390 Learn how water density changes with temperature and ice is less dense than water. The sixth column is the density of the vapor. Water is less dense when it in its solid form as ice. Water at 4 degrees Celsius is denser than water at 0 degrees Celsius. The fifth column is the work PΔ V done by each gram of liquid that changes to vapor. Become a member to unlock this answer Create your account. The fourth column is the heat of vaporization of each gram of liquid that changes to vapor. The third column is the heat content of each gram of the liquid phase relative to water at 0 ☌. From 0 to 100☌ the pressure is 1 atm, and for temperatures >100☌, the pressure is equal to water saturation pressure. Pressure of the equilibrium is given in the second column in k Pa. Specific gravity (SG) for water is given for four different reference temperatures (4, 15, 15.6 and 20☌). 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. Where P is equilibrium vapor pressure in k Pa, and T is temperature in kelvins.įor T = 273 K to 333 K: A = 7.2326 B = 1750.286 C = 38.1.įor T = 333 K to 423 K: A = 7.0917 B = 1668.21 C = 45.1.ĭata in the table above is given for water–steam equilibria at various temperatures over the entire temperature range at which liquid water can exist. The Density of Water At Room Temperature. Vapor pressure formula for steam in equilibrium with liquid water: log 10 ⁡ P = A − B T − C, At 4 C water has its maximum density of 1000 kg/m3. The values below 0 ☌ refer to supercooled water.Įlectrical conductivity of highly purified water at saturation pressure Temperature, ☌ In the metric system a volume of water was used to define the unit of mass. Liquid physical properties Temperature dependence of the surface tension of pure water Temperature dependence of the density of ice and water Velocity of sound in water Water’s density at 23 degrees Celsius is a crucial factor in many practical applications. The reason for this is due to the same principle mentioned earlier the density of water decreases as the temperature increases.

K) at 90 ☌ħ5.94 J/(mol K) and 4.2159 J/(g At 23 degrees Celsius, the density of water is 997.77 kg/m3, which is slightly less than the density at 4 degrees Celsius.

K) at 40 ☌ħ5.30 J/(mol K) and 4.1806 J/(g As the temperature of warm water decreases, the water molecules slow down and the density increases.

At 4 degrees Celsius, water is at its densest, with a density of 1000 kg/m3. This results in an increase in the density of water. As the temperature decreases, the movement of water molecules slows down, allowing them to pack more closely together. Find the density of water at 4☌ in different units and formats with this conversion chart and calculator.
