Water Density At Room Temperature

The density varies with temperature but not linearly.

Water density at room temperature.

This equation water density by temperature is used in 1 page show. This equation water density by temperature references 2 pages show. D regular hexagonal ice is also less dense than liquid water upon freezing the density of water decreases by about 9. It s no coincidence that water has a density of 1.

The density of water varies according to temperature and the degree of purity. 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 room temperature i e 22 c the density of water in kg m 3 is 997 77. The output density is given as g cm 3 kg m 3 lb ft 3 lb gal us liq and sl ft 3.

As the temperature increases the density rises to a peak at 3 98 c 39 16 f and then decreases. Let s look at the density of water at 25 deg c and compare that to a higher temperature 80 deg c. The calculator below can be used to calculate the liquid water density at given temperatures. Freezing water expands over 9 by volume and ice floats on water because it is lighter.

However water s exact density depends on both the air pressure and the temperature of. So 1g 1cm 3 1 g cm 3 giving water its easy to remember density. At 4 degrees celsius pure water has a density of 1g ml or 1kg l and a specific gravity of 1. In other words at the same temperature the density of water in g ml or g cm 3 is 0 99777.

Online water density calculator. Density of pure water is a constant at a certain temperature not depending on sample. The logic is to divide the value of kg m 3 by 1000 to get pure water density in g ml. Temperature must be within the ranges 0 370 c 32 700 f 273 645 k and 492 1160 r to get valid values.

The chart at right give the density in kg m 3 divide by 10 3 to get the density in g ml.
