When reading the volume of fluid in a graduated cylinder the eye should be .?
Level with the bottom of the fluid's meniscus
Reading the volume of liquid inside the graduated cylinder?
Always read from the bottom of the meniscus (where the liquid reaches up the side of the container).
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.
If you have a 100.0-mL graduated cylinder containing 50.0 mL of water. You carefully place a 129-g piece of brass of density 8.56 gmL into the water. What is the final volume reading in the cylinder?
The water will rise by the volume of the brass: volume = mass/density = 129g / 8.56 g/ml ≈ 15.1 ml → final reading ≈ 50.0 ml + 15.1 ml = 65.1 ml
What is the comparison of the volume of space between the piston's top surface and the top cylinder at BDC and TDC is called?
The answer is Compression Ratio. You should try reading the Study Unit it really helps!
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. ...
How does a piece of metal in a graduated cylinder of water allows you to figure out the volume?
The reading on the graduated scale is taken before and after the metal is lowered into the cylinder . The second reading is subtracted from the first. This gives the volume of the metal in cubic centimetres.
When reading a graduated cylinder you should have it at?
You should read a graduated cylinder at eye level. See the related link for rules regarding menisci.
Are correct procedures for reading the volume of water in the graduated cylinder?
Water in a glass graduated cylinder adheres to the sides of the cylinder, forming a meniscus which is an upward curve. When reading volume in a cylinder, look at the meniscus at eye level. Read the volume at the bottom of the curve.
What aspect of your measurement would be hurt if you had an accurate graduated cylinder but were very sloppy in reading it?
precision
When reading the volume of fluid in a graduated cylinder the eye should be .?
Level with the bottom of the fluid's meniscus
Why is it important to keep the graduated cylender on a flat surface when reading the meniscus?
it is important to keep the graduated cylinder on a flat surface when reading the meniscus so that your groogies dont escape and so that the results are good
When reading the volume of a liquid in the graduated cylinder or you must read from the bottom of the?
You must read from the bottom of the meniscus. In a narrow, graduated glass cylinder, water has a slightly domed surface, with the centre being higher than the side, so giving a false reading if the centre height is taken.
Why is volume of the NaCl solution determined through a mass and density calculation rather than reading the graduated cylinder?
It is not a rule.
What are the rules for reading a graduated cylinder?
Read volume from the bottom of the meniscus (the crescent shaped pattern that many liquids form.)
Where do you read the volume in the graduated cylinder?
Graduated cylinders are marked with lines showing the various volumes that are reached by fluid in the cylinder. That is why they are called graduated. If they did not have such markings they would just be ordinary cylinders. So, you see what marking the fluid reaches. That's how you measure the volume. You are just reading it off the cylinder, much the way you read length off a ruler.
What three things should you remember to do when reading a graduated cylinder?
The numbers and make sure it's a exact amount you want or whatever .-.
