Term | Definition |
---|---|
atoms | the basic particle from which all elements are made |
elements | a pursubstance that can be broken down |
weight | a measure of force of gravity on an object |
mass | a measure of how much is in an object |
volume | the amount of space that mater takes up |
matter | anything that has mass that takes up space |
question | to ask for information |
liquid | having a consistency like that of water or oil, i.e., flowing freely but of constant volume |
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 |
accuracy | the quality or state of being correct or precise |
calibration | the 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. |
meniscus | the curved upper surface of a liquid in a tube. |
presition | the quality, condition, or fact of being exact and accurate |
triple beam balence | The 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. |
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 |
international system of mesurment |
