Find the right glass or plastic graduated cylinder for your application. A graduated cylinder is meant to be read with the surface of the liquid at eye level, where the center of the meniscus shows the measurement line. A meniscus may be either concave or convex. Each marked line on the graduated cylinder represents the amount of liquid that has been measured. Log in for more … The bottom of the meniscus is used to measure the volume of a liquid in apparatus such as a graduated cylinder. important pieces of information: You must determine (1) how the scale is increasing with each graduate, (2) where you should measure from, (3) and what metric unit to use for the measurement. Place the graduated cylinder from step 5 on a flat surface. Does water have a skin? Goal: Fill a graduated cylinder with a given amount of water. Search for an answer or ask Weegy. 3. For other activities in the lab, there are more suitable pieces of scientific equipment available. So the liquid "sticks" to the side of the container. 250:5 means count by 5’s! 2.Start at the lower of the 2 graduates and count between the lines between it and the next numbered graduates. The glass cylinder has etched marks to indicate volumes, a pouring lip, and quite often, a plastic bumper to prevent breakage. Some liquids, like mercury, have a convex meniscus because the opposite is true - the molecules of the liquid are more strongly attracted to each other than the walls of the container. Q. They are extensively used in chemistry and biology labs, where quantities of accurately measured liquids need to be used. Graduated Cylinder Size. Read the water's volume by the bottom of the meniscus. New questions in Physics. M. The fluid in a graduated cylinder should be read at the BOTTOM of the meniscus. Reading this printed meniscus is clearly 7.55 mL, but reading a real meniscus is more difficult and uncertainty exists in the hundredths place. We know that 7 is between 6 and 8, so it is the longer line between 6 and 8. Graduated cylinders are also used to determine displacement, which is a measurement of the change in a volume of water when additional materials are added to it. You need to measure at the bottom of the curve, because if you do it from the top, you would get a wrong reading. The meniscus is the curved surface of the liquid when pour in any beaker or test tube. 14 Questions Show answers. 1.Subtract one graduate from the next highest on the cylinder. Sometimes the meniscus rests exactly on a line marked with a number, such as 7 mL on the graduated cylinder, in which case we would read it as 7.00 mL. 2019 Name: _____ Date: _____ Student Exploration: Measuring Volume Vocabulary: cubic centimeter, diameter, graduated cylinder, meniscus, milliliter, pipette, radius, rectangular prism, sphere, volume, water displacement Gizmo Warm-up When scientists talk about how big something is, they are really talking about its volume, or the amount of space it takes up. 749*553 Size:73 KB.
