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.

This easy science activity demonstrates the difference in density between hot and cold water. It can be a bit messy so you may want to try this outside. We're joined by BASF employee, Casey, and his ...

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 ...

Supercooled water is two of a kind, a new study shows. Scientists have long suspected that water at subfreezing temperatures comes in two distinct varieties: a high-density liquid that appears at very ...

Supercooled water may be a two-for-one deal. A long-standing theory holds that liquid water at temperatures well below freezing is composed of two different arrangements of molecules, one with high ...

Create a colorful tower of liquids that stack on top of each other based on their densities. This experiment demonstrates how different liquids have different densities and why some liquids float ...

Density, denoting the relationship between mass and volume or weight and volume, is a crucial metric for systems that link weight to volume, particularly in mixing or dispensing applications.

Fill each glass with same amount of water Leave one glass just plain water Add 2 TBS of salt into one of the three glasses, stir Add 4 TBS of salt into the second of the three glasses, stir Put one ...

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 ...
