For the description of ocean currents accurate measurements of the density of sea water are of great importance. For this purpose, measuring instruments are needed which reach a small uncertainty. To ...

Scientists have measured the density of liquid iron -- the main component of rocky planet cores -- under conditions similar to Earth's liquid core: 1,000,000 atmospheres and 4,000 degrees Celsius.

Compare the density of water to that of different liquids. Krystal Balmes and Sahil from the Brooklyn Preschool of Science make predictions about the density of water to that of honey, corn syrup, and ...

Density refers to the mass of a material per unit volume. Cured density is determined in an adhesive after the curing (hardening) process. Density measurements are useful for evaluating the uniformity ...

This release is also available in German. For oceanography – and there in particular for the description of ocean currents – accurate measurements of the density of sea water are of great importance.
