Term | Definition |
---|---|
accuracy | the degree to which the result of a measurement, calculation, or specification conforms to the correct value or a standard. |
calibration | he action or process of calibrating an instrument or experimental readings. |
graduated cylinder | A graduated cylinder, measuring cylinder or mixing cylinder is a piece of laboratory equipment used to measure the volume of a liquid. Graduated cylinders are generally more accurate and precise than laboratory flasks and beakers. |
International System of Measurement | The definitions of the other base units are more complicated. The International System of Units 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-a unit of measurement | newton, the absolute unit of force in the International System of Units (SI units). It is defined as that force necessary to provide a mass of one kilogram with an acceleration of one metre per second per second. |
precision | he quality, condition, or fact of being exact and accurate. |
triple beam balance | The Triple Beam Balance is a typical mechanical balance. It has a beam which is supported by a fulcrum. On one side is a pan on which the object is placed. On the other side, the beam is split into three parallel beams , each supporting one weight. |
unit | an individual thing or person regarded as single and complete but whi |
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. |
