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 ...

Although the three states of matter are solid, liquid, and gas, not all substances seem to fit perfectly into one of these groups. Take a look at the substance below and see if you can decide whether ...

The state of matter is a deceptively simple concept. It turns out that any material, no matter what it is made of, can exist in one of three forms: solid, liquid or gas. These are categories of stuff ...

Materials may exist in the Solid, Liquid, and Gas phase. The (p,v,T) conditions determine which phase or phases are in thermodynamic equilibrium. For certain ranges of (p.v,T) more than one phase can ...

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 ...

Researchers report that the way a tissue's cells are arranged can serve as a fingerprint for the tissue's 'phase' -- whether it is more like a solid, liquid, or gas. For example, tumors that are more ...
