Matter
physical substance in general, as distinct from mind and spirit; (in physics) that which occupies space and possesses rest mass, especially as distinct from energy.
State
the particular condition that someone or something is in at a specific time.
Condensation
water which collects as droplets on a cold surface when humid air is in contact with it.
Sublimation
change directly into vapor when heated, typically forming a solid deposit again on cooling.
Freezing
the freezing point of water.
Deposition
the action of depositing something.
Malleable
(of a metal or other material) able to be hammered or pressed permanently out of shape without breaking or cracking.
Ductile
(of a metal) able to be drawn out into a thin wire.
Soluble
(of a substance) able to be dissolved, especially in water.
Density
the degree of compactness of a substance.
Conductivity
the degree to which a specified material conducts electricity, calculated as the ratio of the current density in the material to the electric field that causes the flow of current. It is the reciprocal of the resistivity.
Chemical Property
Chemistry. a property or characteristic of a substance that is observed during a reaction in which the chemical composition or identity of the substance is changed:
Chemical Change
Chemistry. a usually irreversible chemical reaction involving the rearrangement of the atoms of one or more substances and a change in their chemical properties or composition, resulting in the formation of at least one new substance:
Pure Substance
Substance contains 1 type of matter
