Understanding the origin of the dramatic temperature and density dependence of the relaxation time of glass-forming liquids is a fundamental challenge in glass science. The recently established ...

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 ...

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.

Using the large synchrotron radiation facility SPring-8 in Japan, a collaboration of researchers from Kumamoto University, the University of Tokyo, and others from Japan and France have precisely ...

Introduction You probably know that when solid objects are placed in liquid, they can sink or float. But did you know that liquids can also sink or float? In fact, it is possible to stack different ...

It is tempting to think that some materials are always heavier than other materials. For example, someone might say that metal is heavier than air. But it depends on how much of each material there is ...

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.
