Matter 1
| Term | Definition |
|---|---|
| accuracy | the extent to which a given measurment agrees with the standard value for that measurment |
| calibration | to divide or mark with gradations graduations or the other indexes of degree guantit etc. as on a thermometer measuring cup |
| graduated cylinder | a narrow cylinder container marked with horzontal lines to repersent units of measuerment and used to precisley measure the volume of liquids |
| international system of measurement | is the modern form of the metric system and is the world's most widely used system of measurement, used in both everyday commerce and science. |
| liquid | having a consistency like that of water or oil, i.e., flowing freely but of constant volume. |
| mass | a coherent, typically large body of matter with no definite shape. |
| matter | physical substance in general, as distinct from mind and spirit; (in physics) that which occupies space and possesses rest mass, especially as distinct from energy. |
| meniscus | the curved upper surface of a liquid in a tube. |
| newton | the SI unit of force. It is equal to the force that would give a mass of one kilogram an acceleration of one meter per second per second, and is equivalent to 100,000 dynes. |
| precision | the quality, condition, or fact of being exact and accurate. |
| triple beam balance | is used to measure masses very precisely; the reading error is 0.05 gram. With the pan empty, move the three sliders on the three beams to their leftmost positions, so that the balance reads zero. |
| unit | an individual thing or person regarded as single and complete but which can also form an individual component of a larger or more complex whole. |
| volume | the amount of space that a substance or object occupies, or that is enclosed within a container, especially when great. |
| weight | a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing. |
