Question | Answer |
---|---|
a substance made by mixing other substances together | Mixture |
a particular kind of matter with uniform properties | Substance(pure substance) |
an article or substance that is manufactured or refined for sale | product |
a mixture of the same kind | homogeneous mixture |
a mixture diverse in character or content | heterogeneous mixture |
a measure of the amount of matter | mass |
anything that has mass and takes up space | matter |
the smallest unit of an element that maintains the chemical identity of that element | atom |
a pure substance that cannot be broken down into simpler, stable substances and is made of one type of atom | element |
a substance that can be broken down into simpler stable substances. Each compound is made from the atoms of two or more elements that are chemically bonded. | compound |
depend on the amount of matter that is present | extensive properties |
do not depend on the amount of matter present | intensive properties |
a characteristic that can be observed or measured without changing the identity of the substance | physical property |
a change in a substance that does not involve a change in the identity of the substance | physical change |
a physical change of a substance from one state to another | change of state |
matter in the state that has definite volume and definite shape | solid |
matter in the state that has definite volume but an indefinite shape | liquid |
matter in the state that has neither definite volume nor definite shape | gas |
high-temperature physical state of matter in which atoms lose most of their electrons, particles that make up atoms | plasma |
relates to a substance's ability to undergo changes that transform it into different substances | chemical property |
a change in which one or more substances are converted into different substances | chemical change or chemical reaction |
the substance that react in a chemical change | reactants |
the substances that are formed by the chemical change | products |
a blend of two or more kinds of matter, each which retains its own identity and properties | mixture |
uniform in composition | homogeneous |
homogenous mixtures | solutions |
not uniform throughout | heterogeneous |
a fixed composition and differs from a mixture because every sample of a given pure substance has exactly the same characteristics properties, and every sample of a given pure substance has exactly the same composition | pure substance |
a distinct and homogeneous form of matter (a particular solid, liquid, or gas) separated by its surface from other forms. | phase |
the action or process of filtering something | filtration |
purify (a liquid) by vaporizing it, then condensing it by cooling the vapor, and collecting the resulting liquid | distillation |
turn from liquid into vapor | evaporation |
an unusual state of matter that arises because of quantum mechanical effects on a collection of entities called bosons. | Bose-Einstein condensate |
