CP Physical Science Classifying Matter Vocab

compound

• chemical substances made up of 2 or more different elements combined through a chemical reaction

• simple substances that cannot be broken down into simpler substances

• mixtures of two or more compounds that retain their individual properties

• elements that are chemically identical and cannot form bonds with other elements

chemical property

• characteristic that can be observed in a chemical reaction

• a physical change that does not alter the substance

• a measurement of the substance's mass

• a property that remains constant under different conditions

evaporation

• vaporization that occurs on the surface of a liquid below its boiling point and changes from liquid to a gas

• the process of a solid turning directly into a gas without becoming a liquid

• the process of a gas turning into a liquid

• the rapid vaporization of a liquid when it reaches its boiling point

filtration

• technique is used to separate an insoluble solution

• method for dissolving soluble substances

• process of mixing liquids

• way to enhance chemical reactions

distillation

• technique used to separate substances in a mixture by evaporation of a liquid

• method for mixing different liquids together

• process of cooling a gas to form a liquid

• technique for filtering solid particles from a liquid

chemical change

• a substance is transformed into one or more different substances

• the physical state of a substance changes without altering its composition

• the mass of a substance remains constant during the reaction

• the temperature of a substance increases without any reaction occurring

homogeneous mixture

• mixture in which all of the substances are evenly distributed

• mixture that contains different substances that are not evenly distributed

• mixture that can be easily separated by physical means

• mixture that has a uniform composition throughout

pure substance

• has constant chemical composition and properties

• can be separated into simpler substances by physical means

• is always a solid at room temperature

• contains two or more different elements

plasma

• state of matter that has a definite shape and volume

• state of matter that has a definite shape but no definite volume

• state of matter that does not have a definite shape or volume but whose particles have broken apart

• state of matter that is solid at room temperature

solute

• substance in a solution that gets dissolved

• substance that does not dissolve in a solution

• the liquid in which a solute is dissolved

• a mixture of two or more substances
