The units of density depend on the units used for mass and volume. The most commonly used units are grams per cubic centimetre (g/cm³) or kilograms per cubic metre (kg/m³). These balloons are the same ...

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.

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 ...

A collaboration between scientists at Cambridge and UCL has led to the discovery of a new form of ice that more closely resembles liquid water than any other and may hold the key to understanding this ...

Scientists discover zero-sound mode oscillations in super-chilled helium. Scientists have carried out the first investigation of two-dimensional fermion liquids using neutron scattering, and ...

Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. RUBEN: Setting up an experiment, Elliot. ELLIOT: What you doing? RUBEN: Well, I've got three glasses ...

People learn about a food's satiating capacity by exposure and consequently adjust their energy intake. Buffet intake depended on energy density and day of consumption of the test foods (day*energy ...
