State of a substance
•Definitions - state and properties
•State: condition of a system as defined by its properties.
•Quantity: characteristic of a system.
•Property: quantity independent of how it got its current value.
•Extensive property: sum of its values for all parts of the
system.
•Intensive property: independent of system size.
•Specific property: extensive property specified w.r.t another.
•Molar property: extensive property specified w.r.t mole.
•Measurable properties: capable of being measured directly.
•Derived properties: derived from measurable properties.
STATES OF SUBSTANCES
GENERAL
•Main 4 states of substances:
–Plasma state
–Gas state
–Liquid state
–Crystal state
•3 pseudo-stable states: (reading yourself)
–Amorphous solid state (vô định hình)
–Slow freezing state
–Slow boiling state
–Some substances have the mesomorphic (trung gian) state
between liquid ans solid: Liquid crystal
Liquid-crystal state
– A mesomorphic state having long-range orientational order
and either partial positional order or complete positional
disorder. (isotropic = đng hưng)
