| Term | Definition |
|---|---|
| accuracy | the quality of being near the true value |
| balance | equipment used to measure mass |
| boiling point | temperature at which a liquid turns to gas |
| brittle | breaking into small pieces if bent or pressed |
| calibrate | to mark off lines on measuring equipment for the desired unit |
| centimeter cubed | cm3; a unit of volume derived from length times width times height |
| chemical property | a characteristic of a pure substance that describes its ability to change into different substances |
| compress | to squeeze or press together |
| condensation point | temperature at which a gas to turn liquid |
| conductor | a material that does allow electricity or heat to pass through easily |
| density | an object’s mass compared to its volume. Mass divided by volume is density. |
| deposition | a gas changing into a solid without changing into a liquid |
| dissolve | to break into pieces too small to be seen |
| ductile | able to be pulled into long, thin wires |
| flexible | able to bend without breaking |
| freezing point | temperature at which a liquid turns to solid |
| gas | a state of matter having indefinite volume, indefinite shape, with particles bouncing around and not touching each other |
| graduated cylinder | equipment use to measure liquid volume |
| gram | an SI unit to measure mass; 1g = 0.001kg; there are 1000g in 1 kilogram |
| gram per centimeter cubed | g/cm3; a derived unit used to measure density of a solid |
| gram per milliliter | g/mL; a derived unit used to measure density of a liquid |
| insulator | a material that does not allow electricity or heat to pass through easily |
| kilogram | the SI base unit to measure mass; 1 kg = 1000g |
| kinetic theory | a physics theory that all matter is made of moving particles in random motion |
| liquid | a state of matter having definite volume, indefinite shape, with particles touching, and sliding around each other |
| liter | the SI unit to measure volume of liquids |
| luster | shininess; the property of something that shines with reflected light. |
| magnetic | material that is attracted to magnets |
| malleable | able to be hammered or pressed into flat sheets |
| mass | he amount of matter (atoms) in a substance; measured in grams and kilograms |
| matter | anything that has mass and volume (takes up space) |
| melting point | temperature at which a solid turns to liquid |
| meniscus | the curve on the upper surface of a liquid in a container caused by surface tension |
| milliliter | an SI unit to measure volume of liquids; 0.001 of a liter; there are 1000 mL in 1 Liter. |
| phases of matter | solids, liquids, gases, and plasma; also called states of matter |
| physical property | a characteristic of a pure substance that can be observed without changing it into another substance |
| plasma | a state of matter consisting of ionized (electrically charged) particles |
| precision | the amount of detail or refinement in measurement |
| solid | a state of matter having definite volume, definite shape, with particles vibrating, touching and locked into place |
| soluble | able to dissolve |
| states of matter | solids, liquids, gases, and plasma; also called phases of matter |
| sublimation | turning from solid to gas without turning into a liquid |
| texture | how something feels, especially whether it is bumpy or smooth |
| unit | a single, undivided whole; a quantity chosen as a standard for measurement |
| volume | the amount of space an object takes up or the amount of space a container holds |
| weight | the measure of the pull of gravity on a substance |
