We do not know as we have not found any dark matter to examine. The only way we detect it and know it exists is due to its gravitational attraction of the ordinary matter we can see.
One speculation when neutrinos were discovered to have tiny nonzero masses was that dark matter might be neutrinos. Another speculation is that dark matter is only ordinary matter, but its in another separate universe in a shared higher dimensional spacetime. Nobody knows.
There are 3 basic states of matter Solid Liquid Gas
Solid, liquid, gas are classical states of matter.
solid, liquid, and gases
Condensation (gas to liquid or solid or liquid to solid), vaporization (liquid or solid to gas), sublimation (solid to gas), solidification (liquid to solid), or melting (solid to liquid).
A solid, or even a gas. And back again (improved)liquid is a state of matter, which can be a solid, liquid, or gas. therefore, liquid can be changed into a solid or a gas. to do so, just change the temperature of the matter. :-D
Which solid liquid gas?
The kinds of matter are solid, liquid, and gas.
There are 3 basic states of matter Solid Liquid Gas
Solid, liquid, and gas.
The states of matter are solid, liquid and gas. A solid melts to become liquid and a liquid evaporates to become gas. Sublimation is the direct change from solid to gas.
solid to liquid: meltingliquid to gas: vaporization
Liquid to gas, solid to liquid, and liquid to solid
The three principle states of matter are solid,liquid,gas
Matter is different solid liquid and gas
Solid, liquid, gas are classical states of matter.
solid, liquid, gas, plasma
The [main] states of matter are solid, liquid, and gas. They usually move like this: Solid ---> Liquid ---> Gas However, matter can jump from solid to gas and vice versa, but it usually doesn't.
