- Matter actually has six states—solid, liquid, gas, and ionized plasma. Fifth and sixth states come from the following:
- Particles, whether elementary (electrons) or composite (protons, neutron etc) are divided into two fundamental categories—fermions and bosons. Why? Because when we measure fermions spin or angular momentum we always get values that are quantized in half integer values of Plank’s constant —eg. +-1/2, +-3/2.
Bosons on the other hand have whole integer values —eg. 0,+-1, +-2.
There is not a single particle that we know of making up our reality that doesn’t follow this rule.
- Pauli’s exclusion principle which states that not two fermions can occupy exact same quantum state as on another.
- Combining the above give us two more states of matter under certain lab conditions: Bose-Einstein Condensates and Fermionic Condensates.
Cool! Have you been studying physics for a while?
Lookee this- Some States of Matter
Yeh a little bit here and there.
