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 measuring with a graduated cylinder you pour liquid into a what?
When measuring with a graduated cylinder, you pour the liquid into the cylinder to a precise level. Read the measurement at the bottom of the meniscus, which is the curved surface of the liquid. Be sure to read the measurement at eye level for accuracy.
What is the fill line of a graduated cylinder called?
The fill line of a graduated cylinder is known as the meniscus. It is the curved surface of a liquid in the cylinder caused by the surface tension between the liquid and the glass. Scientists must take measurements at the bottom of the meniscus for accuracy.
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).
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 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."
How can you use volume and meniscus in the same sentence?
To accurately measure the volume of a liquid in a graduated cylinder, you must read the measurement at the bottom of the meniscus, which is the curved surface of the liquid caused by surface tension.
How do you read a graduated cylindar with urine?
To read a graduated cylinder with urine, place the cylinder on a flat surface at eye level, ensuring the liquid is not spilling or forming bubbles. Read the measurement at the bottom of the meniscus, the curved surface of the liquid. Take note of the volume marking that aligns with the bottom of the meniscus for an accurate reading.
Do you measure volume to the top or bottom of the muniscus?
When measuring the volume of a liquid in a graduated cylinder or similar container, the volume is typically measured to the bottom of the meniscus (the curved surface of the liquid). This is because the liquid forms a concave shape at the edges due to surface tension, and the volume should be read at the lowest point of the curve for accuracy.
When measuring out a liquid in a graduate th upper surface of the liquid is called?
The upper surface of the liquid in a graduated cylinder is called the meniscus. It appears curved due to surface tension, and the measurement should be read at the bottom of the meniscus for an accurate volume reading.
How do you used gra duated cylinder?
To use a graduated cylinder, place it on a flat surface and pour the liquid you want to measure into it. Make sure to read the measurement at eye level from the bottom of the meniscus, which is the curved upper surface of the liquid. Be cautious with handling to prevent spills and inaccuracies in measurement.
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.
