Explore the fundamental concept of matter in physics, everything that makes up the physical world around us. Matter is not ...

Liquids typically have a lower density than solids. In gases the particles are far apart, moving quickly in random directions with a lot of empty space between them. So they have the lowest ...

Recent physics studies have found that light can sometimes flow in unexpected ways, behaving like a so-called "superfluid." ...

While gas pycnometry is best suited for solid skeletal density measurements, experimental parameters can be optimised for slurries and/or liquids that have some vapor pressure.

The four fundamental states of matter are solid, liquid, gas and plasma, but there others, such as Bose-Einstein condensates and time crystals, that are man-made.

Chapter 1 : Matter—Solids, Liquids, and Gases 1.1: Molecules Matter; 1.2: Molecules in Motion; 1.3: The Ups and Downs of Thermometers; 1.4: Moving Molecules in a Solid; 1.5: Air, It’s Really ...

It can be found inside gas giants such as Jupiter and is briefly created during meteorite impacts or in laser fusion ...

Water is unique. It is one of the only substances that can exist in nature as a solid, liquid and gas at the same time under ambient conditions (think of solid ice over a pond, which is liquid ...

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.

Whether a substance is a solid, liquid, or gas at a certain temperature depends on the balance between the motion of the particles at that temperature and how strong their ... (We’ll get to this when ...
