Science Unit 2 vocabulary test

A characteristic of matter that can be observed or measured and can be changed without changing the matter itself. Matter Physical property Weight Solid Anything that has mass and takes up space Volume Relative density Dissolve Matter The amount of matter an object has Mass Matter Weight Volume The measure of the amount of GRAVITY acting on an object's mass Relative density Mass Volume Weight The amount of SPACE taken up by matter Volume Matter Physical property Weight A comparison of an object's density to the density of water. LESS DENSE= fLoat MORE DENSE=sink Volume Weight Relative density Solubility The ability of a substance to dissolve in another substance. Solubility Dissolve Mixture Solution A state of matter that has a FIXED SHAPE AND VOLUME Liquid Solid Gas Mixture A state of matter that has a FIXED VOLUME, but its shape changes to match the shape of its container Gas Solid Liquid Matter A state of matter that DOES NOT have a fixed shape or volume. Liquid Mixture Solid Gas A combination of two or more substances that DO NOT join together to form a new substance. The substances maintain their physical properties. Solution Mixture Dissolve Gas A special mixture in which the substances spread out evenly between one another and cannot be seen. Mixture Dissolve Magnetism Solution To form a solution with another substance. Dissolve Mixture Solution Solubility The ability of an object to be attracted to a magnet or not Conductivity Magnetism Conductor Insulator The ability or power to conduct or transfer heat or electricity Magnetism Insulator Conductivity Soluble An object that does allow the flow of thermal energy or electricity. Insulator Conductor Conductivity Magnetism An object that does NOT allow the flow of thermal energy or electricity Conductivity Conductor Thermal Conductivity Insulator An object that is attracted to a magnet Magnetic Non-magnetic Conductor Conductivity An object that is NOT attracted to a magnet Non-magnetic Magnetic Insulator Conductor A substance that does dissolve into another substance Ex. -honey, sugar, salt Mixture Solution Insoluble Soluble A substance that does not dissolve into another substance. Ex. -sand, oil, dirt Soluble Insoluble Solution Mixture Ability for matter to conduct (transfer) thermal energy or insulate (keep from transferring) thermal energy Electrical Conductivity Conductor Thermal conductivity Conductivity Ability for matter to conduct (transfer) electricity or insulate (keep from transferring) electricity Conductivity Conductor Thermal Conductivity Electrical Conductivity
