8. Particles of liquids are tightly packed, but are
far enough apart to slide over one another.
Liquids have an indefinite shape and a
definite volume.
12. A plasma is an ionized gas.
A plasma is a very good conductor of
electricity and is affected by magnetic
fields.
Plasma, like gases have an indefinite shape
and an indefinite volume.
15. A Bose–Einstein condensate (BEC) is a state of matter of a dilute
gas of bosons cooled to temperatures very close to absolute zero
As atoms cool, they behave more like waves and less like
particles. When cooled enough, their waves expand and begin to
overlap. This is similar to steam condensing on a lid when it is
boiled. The water clumps together to form a drop of water, or
condensate. The same occurs with atoms, only it is their waves
that merge together. Bose-Einstein condensates are similar to
laser light. However, instead of photons behaving in a uniform
manner, it is the atoms that exist in perfect union. Like a drop of
water condensing, the low-energy atoms merge together to form
a dense, indistinguishable lump.
