The traceability of the density value of water can be obtained by measuring its temperature, atmospheric pressure and calculating its value by the appropriate formula in regards to the required ... The equation of state defines the relationship between pressure, temperature and density at any point in the atmosphere, but it does not determine the pressure or temperature in the first place. Only once you have determined the pressure and temperature can you then use the equation of state to calculate the density. Density is calculated by the dividing the mass by the volume, so that density is measured as units of mass/volume, often g/mL. If both water samples are at the same temperature, their densities should be identical, regardless of the samples’ volume.

The density of liquid water is approximately 1.0 g/mL. The chart at right give the density in kg/m 3. Divide by 10 3 to get the density in g/mL. Let's look at the density of water at 25 deg C and compare that to a higher temperature, 80 deg C. The density decreases from 0.9970 g/mL to 0.9718 as it is heated. • What is the density of dry air with a temperature of 20 oC and a pressure of 800 hPa? – Use the ideal gas law: P = R d T – Need to express all quantities in S.I. units • T = 20 oC = 20+273.15 K = 293.15 K • P = 800 hPa = 800 x 100 Pa = 80000 Pa – = P/R d/T = 80000/287/293.15 = 0.95 kg/m3 R is the universal gas constant.
