States of Matter Flashcards
What is kinetic theory?
describes the arrangement of solid liquid and gases
What is the arrangement of a solid?
very close, neat pattern
How do solids move?
vibrations in fixed position
What is the energy of a solid?
low
What is the arrangement of a liquid
close, randomly arranged
How does a liquid move?
move around each other
What is the energy of a liquid?
greater
What is the arrangement of a Gas
far apart, randomly arranged
How does a gas move?
quickly in all directions
What is the energy of a gas?
Highest
What is it called from going from solid to liquid?
melting
What is it called from going from liquid to solid?
freezing/solidifying
What is it called from going from liquid to gas?
boiling/evaporating
What is it called from going from gas to liquid?
condensing
What is it called from directly going from solid to gas?
sublimation
What is a pure substance?
only one element or compound
What is a mixture?
two or more different substances NOT chemically joined
What is filtration?
separates insoluble solid from a liquid
what does insoluble mean?
unable to dissolve in a particular solvent
What is crystallization?
produces solid crystals from a solution
What is a solvent?
the liquid in which the solute dissolves to form solution
How is crystallization done?
- put solution in basin
- warm solution
- stop heating before all is evaporated
What is simple distillation?
separates a solvent from a solution
What is fractional distillation?
a mixture of substances is distilled and evaporated components are collected
