Matter Vocab Flashcards
a homogeneous mixture of metals, or a mixture of a metal and a non-metal in which the metal is the major component.
Alloy
a material’s ability to absorb energy before fracturing.
brittleness
any change that results in the formation of a new chemical substance.
chemical change
a characteristic of a substance that’s observed during a chemical reaction.
chemical property
parts of a mixture are separated based on the ability of each dissolved component to travel through materials at different speeds.
chromatography
occurs when a material catches fire at a temperature above 43 degrees Celcius.
combustibility
any substance formed from two or more elements that have been joined together chemically.
compound
the phase change that occurs when water vapor cools down to form liquid water.
condensation
the temperature at which a gas turns into a liquid at standard pressure.
condensation point
the separation of a pure solid substance from a solution containing the dissolved substance.
crystallization
the amount of mass per unit volume.
density
when a gas changes directly into a solid without going through the liquid phase.
deposition
the process that separates homogenous mixtures based on the different boiling points of the substances.
distillation
the amount of heat in a system at constant pressure.
enthalpy
occurs on the surface of a liquid as it changes into a gas.
evaporation
a physical process used to separate solids from liquids by passing them through a barrier.
filtration
occurs when a material catches fire at a temperature below 43 degrees Celcius.
flammability
when a liquid turns into a solid.
freezing
the temperature at which a liquid turns into a solid.
freezing point
a combination of two or more substances in which the original substances are separated into physical distinct regions.
heterogeneous mixture
a combination of two or more substances that have uniform composition and chemical properties throughout; also known as a solution.
homogeneous mixture
any force that can hold or repel particles.
intermolecular force
how readily a material’s shape can be changed.
malleability
anything that has mass and takes up space.
matter
when a solid turns into a liquid.
melting
the temperature at which a solid turns into a liquid.
melting point
a combination of two or more pure substances in which each pure substance retains its individual chemical properties.
mixture
a special type of physical change in which a substance transitions among the states of matter, solid, liquid, and gas, but the chemical properties of the substance remain the same.
phase change
a change which alters a substance without altering its composition.
physical change
a characteristic that can be observed or measured without changing the chemical makeup of a substance. Types include color, odor, texture, boiling point, melting point, and density.
physical property
the relative ability of a substance to undergo a chemical reaction.
reactivity
a combination of two or more substances that have uniform composition and chemical properties throughout; also known as a homogeneous mixture.
solution
when a solid transitions into a gas without going through the liquid phase.
sublimation
a measure of the random kinetic energy in a sample of matter.
temperature
the phase change from liquid to gas.
vaporization
