Calibration | each of a set of graduations on an instrument |
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 | International System of Units (SI), French Système Internationale d'Unités, international decimal system of weights and measures derived from and extending the metric system of units |
Liquid | having a consistency like that of water or oil, i.e., flowing freely but of constant volume. |

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 | the 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 | a quantity chosen as a standard in terms of which other quantities may be expressed. |
Volume | he 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. |
