gas The state of matter
distinguished from the solid and liquid states by relatively low density and viscosity (stickiness), relatively great expansion and contraction with changes in pressure and temperature, and the spontaneous tendency to become distributed evenly throughout any container.
They are in the state of matter
for which rest-mass is definitely zero [m.sub.0] = 0 but the relativistic mass is imaginary.
All these atoms form a weak bond, creating a new, exotic state of matter
at cold temperatures, referred to as "Rydberg polarons."
This is what a quantum spin liquid - a state of matter
first proposed in the 1970s, but discovered only over the past few years - is.
And here's the fascinating bit: physicists have now observed the same "near perfect liquid" state of matter
at temperatures near absolute zero.
"A microsecond after the Big Bang, there was a state of matter
that no one was able to investigate until very recently.
IMAGINE a fridge-size hunk of solid--a state of matter
with mass and volume made up of tightly bound molecules--that weighs just one pound and can hold up the weight of a Honda Civic.
Summary: TEHRAN (FNA)- Using ultracold atoms, researchers at Heidelberg University have found an exotic state of matter
where the constituent particles pair up when limited to two dimensions.
The condensed state of matter
the researchers worked on is somewhat similar to what's known as the Bose-Einstein condensate. Named after physicists Satyendra Nath Bose and Albert Einstein, it is a state of matter
created when atoms are cooled to a temperature close to absolute zero (0 Kelvin or -459.6 degrees Fahrenheit).
Called a quark gluon plasma, it's a state of matter
that existed in the milliseconds after the Big Bang 13.7 billion years ago.
Evaporation is a type of phase change, the process by which a substance changes from one state of matter
into another (for example, liquid changing into gas).
In April, scientists announced that they had discovered a brand-new state of matter
- one that wasn't solid, liquid, gas or plasma.
