We all know from middle school science class that matter changes between a solid, a liquid, and a gas when you change the temperature or pressure acting on it. (Yes, some elements will change directly ...

Conduct investigations to identify characteristics of gases, and learn about the gases that make up our atmosphere. Explore features of solids, liquids, and gases while noticing that substances can ...

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. When you purchase through links on ...

THE tenets of physics can seem carved in stone. The speed of light is a constant. There are four fundamental forces. Theoretically, rules like these are open to revision. But new contenders had better ...

A series of experiments studying complex plasmas is taking place on board the international space station ISS. Physicists from Germany will use these experiments to study fundamental structure forming ...

Water may seem boring, but it's way weirder than it looks. Scientists in Japan have now shown that when confined to tight spaces, water molecules can behave like both a solid and a liquid ...

Two years ago, Ars was invited to Huntsville’s Marshall Space Flight Center to watch a team of engineers from NASA and Aerojet Rocketdyne fire up some 50-year old rocket components—specifically, the ...

THE low temperature exhibition, which is being arranged by the Science Museum, has already been mentioned in these columns; we now learn from the director of the Museum, Col. E. E. B. Mackintosh, that ...
