How is liquid volume measured?
Liquid Volume Measuring Devices: The Graduated Cylinder and Buret Like weighing, measuring liquid volume is a fundamental and frequently encountered lab task. However, liquid volume is frequently measured using either a graduated cylinder or a buret. As the name implies, a graduated cylinder is a cylindrical glass (or plastic) tube sealed at one end with a calibrated scale etched (or marked) on the outside wall. Graduated cylinders come in a range of sizes (volume capacities), and much like a measuring cup, volume is measured by adding liquid to the cylinder and comparing the liquid level to the graduated scale. The measured volume corresponds to the volume of liquid contained in the cylinder. Hence, the graduated cylinder and devices like it (volumetric flasks, Erlenmeyer flasks, and beakers) are classified as to-contain (TC) devices. The volume of liquid in the graduated cylinder is obtained directly by reading the calibrated scale. In most situations, the liquid will be water or an aqueous solution.The liquid surface is curved (U-shaped) rather than horizontal due to the relatively strong attractive force between water and glass. (The curved surface is called the meniscus.) As a general rule, the bottom of the meniscus is taken as the liquid level in the cylinder (and any other volume measuring device). The scale divisions on a graduated cylinder are generally determined by its size. For example, the 50-mL graduated cylinder is divided into 1 mL increments. However, the scale of a 10-mL graduated cylinder is divided into 0.1 mL increments, and the scale of a 500-mL graduated cylinder is divided into 5 mL increments.The graduated cylinder scale is a ruled scale, and it is read like a ruler. The scale is read to one digit beyond the smallest scale division by estimating (interpolating) between these divisions. With a 50-mL graduated cylinder, read (and record) the volume to the nearest 0.1 mL. The 10-mL graduated cylinder scale is read to the nearest 0.01 mL and the 500-mL graduated cylinder scale is read to the nearest milliliter (1 mL).A buret is a scaled cylindrical tube attached to a stopcock (valve). A buret is designed to dispense or transfer a precisely measured volume of liquid to another container. The volume of liquid dispensed is determined by reading and recording the buret scale which corresponds to the liquid level in the buret before any liquid is transferred, Vinitial (or Vi),and after the transfer is complete, Vfinal (or Vf). The volume of liquid transferred is obtained by difference (Vf - Vi) and it is sometimes designated as Vt.Burets are available in a limited range of sizes; the most common size is 50-mL. The scale of a 50-mL buret is divided into 0.1 mL increments. Therefore, when the liquid level in a buret is read, it is read (and recorded) to the nearest 0.01 mL. Water or aqueous solutions are the most common liquids used with a buret, and like the graduated cylinder the bottom of the meniscus is taken as the liquid lever. The buret and devices like it (pipet and syringe) is classified as a to-deliver (TD) devices.
What is the liquid curve in a graduated cylinder called?
The liquid curve is called a meniscus.
What piece of equipment is used to find the volume of a liquid?
A Graduated Cylinder
How do you know that the rock in the figure with the graduated cylinder has a volume of 10 mL?
The level of the liquid in the cylinder rose by 10 mL when the rock was submerged in the liquid.
The curved surface at the top of a liquid in a graduated cylinder is called?

When using the measuring cylinder do you talk the measurement at the side of the cured surface or the curved surface?
I think you are talking about a graduated cylinder. When measuring liquids in a grad. cylinder you should read at the bottom of the miniscus ( the curved surface of the water or other liquid).
What is the the bottom of a curved line in a graduated cylinder?
The "bottom of a curved line" made by the liquid in a graduated cylinder could be called the "measuring line" or "reference line" in the application of that piece of labratory equipment. The curved surface of the liquid itself is called the meniscus, and we look to the bottom of the meniscus to make our reading as to the volume of the liquid in the graduated cylinder. The liquid in the cylinder "grabs" the sides of the cylinder and "pulls itself up" just a bit, and that creates the curve in the surface of the liquid. And that curve, the meniscus (which is from the Greek word for crescent), leaves us with a problem: where do we "read" the volume marked off by the graduations along the side of the cylinder? And the answer is, "At the bottom of the meniscus."
When reading a graduated cylinder you look at?
When you read a scale on the side of a container with a meniscus, such as a graduated cylinder or volumetric flask, it's important that the measurement accounts for the ... For mercury, take the measurement from the top of the meniscus. ...
What is the crescent shaped surface of liquid that form in pipettes and graduated cylinder?
The crescent shaped surface of liquid that forms in pipettes and graduated cylinders is called a meniscus.
Uses of a graduated cylinder?
1. Look at the liquid at eye level 2. Measure from the meniscus (the curved line at the surface of the liquid) 3. Be sure to measure your intervals (the value of each measurement line on the cylinder)
How do you use measuring cylinder?
A graduated cylinder is used to measure liquid volume in milliliters, mL. When you place a liquid into a glass graduated cylinder, you will see that the "line" at the top of the column of liquid is actually curved downward. This is called the meniscus. When you measure the liquid volume, you record the volume in mL at the bottom of the meniscus.
What should you look at to measure a volume of water in a graduated cylinder?
Place the cylinder on a flat surface. Read the volume contained in a graduated cylinder or volumetric flask, by comparing the bottom of the meniscus (the curved surface of the liquid),at eye level, to the nearest graduation or ring.
What is the curve of the top surface of water in a graduated a graduated cylinder called?
Adhesion is responsible for the surface of the water in a graduated cylinder that is slightly curved at the sides.
What is a meniscus why is it necessary to know about it when necessary liquids?
Meniscus is the curved surface of a liquid in a container; to measure correctly the volume in a graduated cylinder it is necessary to take into account the meniscus type, convex or concave.

A graduated cylinder used to find what of a liquid?
A graduated cylinder is used to find the VOLUME of a liquid.
