Term
Ductile
Definition
To be stretched into wires
Term
Malleable
Definition
To be hammered into shape
Term
Alloys
Definition
are materials that are made of a metal ixed with another element
Term
states of matter
Definition
solids, liquids and gasses make up the three states of matter
Term
Melting
Definition
Change of state from solid to liquid when heated
Term
Boiling
Definition
Change in state from a liquid to a gas when heated
Term
Evaporation
Definition
Change in state from a liquid to a gas when heated this only happens to the surface liquid, it does not have to be at the boiling point for evaporation to occur
Term
Condensing
Definition
change in state from gas to a liquid when cooled
Term
Freezing
Definition
change in state from a liquid to a solid when cooled
Term
Subliming
Definition
change in state from a solid to a gas or the reverse for re-subliming
Term
Melting point
Definition
the temperature in which all particles of a substance have changed from a solid to a liquid state
Term
Boiling point
Definition
the temperature at which all particles of a substance have changed from liquid to gas states
Term
A physical change
Definition
no new substance is made just the arrangement of the particles, it is easy to reverse
Term
Diffusion
Definition
the movement of a substance from a high concentration to a low concentration
Term
Expansion
Definition
the increase in size of a substance due to increased movement of particles and energy
Term
Contraction
Definition
the decrease in size of a substance due to decreased movement of particles and loss of energy
Term
Dissolving
Definition
Solid particles totally mix with liquid particles.
Term
Solute
Definition
A solid that is dissolved in a liquid
Term
solvent
Definition
the liquid which dissolves the solid
Term
solution
Definition
a mixture of the solvent and solute
Term
Soluble

a substance that can not be dissolved
Term
filtration
Definition
process used to separate insoluble solids from liquidsby filtering them
Term
Chromatography
Definition
method of separating substances that depend on the different speeds that each substance moves through a particular material
Term
Evaporation
Definition
process by which more energetic particles on surface of liquid turn into a gas at temperature lower then boiling point
Term
Distilation
Definition
a method of purifying liquids which involves the evaporation of the liquid followed by condensation of the gas
