Why do some gases rise in the air while other gases sink? Why do some gases rise in the air while other gases sink? It all has to do with how heavy the molecules are compared to the air itself! Watch ...

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 ...

Students will be able to explain that the density of a liquid has to do with how heavy it is for the sample size. Students will also be able to explain that if a liquid is more dense than water, it ...

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 ...

The Science Siblings, Adam and Paige Jacobson, recruited 4-year-old Tukker and 2-year-old Jayger for a density experiment. They tested whether fruits and veggies float or sink in a bowl of water.

The collaborators are Kazan Federal University, Vereschagin Institute of High Pressure Physics (Russian Academy of Sciences), Queen Mary University of London, Imperial College London, Rutherford ...

A nanoporous material that holds hydrogen at twice the density of cryogenic liquid H2 could address the challenges of large-scale liquid and gas storage that have held this clean fuel back. Hydrogen ...

Scientists have uncovered a key finding to one of water's unique properties: at high pressure and low temperature, liquid water separates into two distinct liquid phases -- one high-density and one ...
