That solid iron inner core of Earth may still hold liquid iron, according to a new study from the University of Utah. Scientists have used seismic waves to research Earth’s inner core ...

In particular, the physical properties of liquid iron—which makes up most of the Earth’s core—have been the subject of much debate among physicists and geoscientists. The problem is that ...

Earth has a mantle of rock that moves like a sluggish liquid. Beneath the mantle is a liquid iron outer core and solid iron inner core. Because Earth and Mars are both rocky planets, and might ...

Further analysis determined that the Martian core is most likely made out of an alloy of liquid iron and sulfur, and that it’s constantly going through convection, with hotter fluid rising and ...

"Even the strongest hurricanes in the solar system seem calm in comparison." WASP-121 b is the definition of an "extreme" exoplanet — it's so hot that it rains droplets of liquid iron.

What makes this battery different is that it stores energy in a unique liquid chemical formula that combines charged iron with a neutral-pH phosphate-based liquid electrolyte, or energy carrier.

As density equals \(\frac{\text{mass}}{\text{volume}}\), the liquid will have slightly lower density. The density of solid iron = 7.8 g/cm 3 The density of liquid iron = 6.9 g/cm 3 A substance ...
