STATES OF MATTER

Nota:

• Plasma is the most abundant form of ordinary matter in the Universe, most of which is in the rarefied intergalactic regions,  and in stars, including the Sun] A common form of plasmas on Earth is seen in neon signs.

Nota:

• A Bose–Einstein condensate (BEC) is a state of matter of a dilute gas cooled to temperatures very close to  −273.15 °C

1. Expansion
2. Contraction

Nota:

• Change of state from a liquid to a gas

1. Evaporation

   Nota:

   • Is vaporisation that occurs at any temperature and only on the surface of the liquid.
2. Boiling

   Nota:

   • Is vaporisation that occurs when a liquid is heated to a specific temperature that is high enough so that all the liquid vaporises
   1. Boiling point

Nota:

• The change of state from gas to a liquid. The condensation point is the temperature at which a gas starts to condense into a liquid. For every substance, its condensation point is the same as its boiling point.
