Water Density At Room Temperature

In other words at the same temperature the density of water in g ml or g cm 3 is 0 99777.

Water density at room temperature. Let s look at the density of water at 25 deg c and compare that to a higher temperature 80 deg c. Density is mass divided by volume ρ m v and water was used as the basis for establishing the metric unit of mass which means a cubic centimeter 1cm 3 of water weighs one gram 1g. The density of water varies according to temperature and the degree of purity. Temperature must be within the ranges 0 370 c 32 700 f 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. However water s exact density depends on both the air pressure and the temperature of. At room temperature i e 22 c the density of water in kg m 3 is 997 77. Freezing water expands over 9 by volume and ice floats on water because it is lighter.

Online water density calculator. Equations and constants density water at stp si by michaelbartmess volumetric temperature expansion coefficient water by michaelbartmess. The density varies with temperature but not linearly. D regular hexagonal ice is also less dense than liquid water upon freezing the density of water decreases by about 9.

This equation water density by temperature is used in 1 page show. Water density specific weight and thermal expansion coefficient definitions online calculator figures and tables giving density specific weight and thermal expansion coefficient of liquid water at temperatures ranging from 0 to 360 c and 32 to 680 f in imperial and si units. At 4 degrees celsius pure water has a density of 1g ml or 1kg l and a specific gravity of 1. The logic is to divide the value of kg m 3 by 1000 to get pure water density in g ml.

As the temperature increases the density rises to a peak at 3 98 c 39 16 f and then decreases. It s no coincidence that water has a density of 1. This equation water density by temperature references 2 pages show. So 1g 1cm 3 1 g cm 3 giving water its easy to remember density.

The calculator below can be used to calculate the liquid water density at given temperatures.
