Why do you have to wet the lead pellet before dropping it into the graduated cylinder when determining the volume?

When using a lead pellet to determine the volume of a liquid, the pellet is wet before being dropped into the cylinder so that it will sink faster. If the pellet was not wet it would take a fraction of a second to start to sink in the liquid.

What is the method used to find the volume of an irregular object using a graduated cylinder?
The method you would use is to take a graduated cylinder, face the markings towards you, fill the cylinder with a liquid that won't react with said object (usually water is fine) to an appropriate measure (around half way depending on the size of the object), record the volume before placing the object in the fluid, place the object in the fluid and record the volume after, subtract the initial from the total (liquid +object's displacement) and you will have the objects volume. However you must be aware that certain objects will float or at least have some amount of buoyancy making determining it's volume harder to ascertain (if at all possible) with this method.
What must you do first before determining gravitational PE?
you must determine hight
How do you find the volume of an odd shaped object?
The best way to find the volume of an irregularly shaped object is to place it in a graduated cylinder full of water or some other liquid, and measure how much the level increased. Since one milliliter is equal to 1 cm3 you simply convert the amount displaced and you have the volume.
73 ml of water followed by 25 ml of juice into 100 ml cylinder?
73 + 25 = 98 means that there is 2 ml of space in the cylinder before there is a risk of the liquid overflowing.
How do you find the volume of an irregular object such as a rock?
Use the Archimedes' method, fill a container with water (right to the top) with a spill tray underneath to catch the water over flow, drop the rock in and measure the amount of water displaced. This method will be about as accurate as you can get.
Why do you have to wet the stone before dropping it into the graduated cylinder?
If you were to drop a dry stone into a graduated cylinder it would pull a lot of air bubbles down with it (they stick to the surface, you should actually be able to see them) and that will give you an erroneous volume.
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.

What is volume by displacement?
Volume displacement is the method used to find the volume of small or irregularly shaped objects by noting the difference in the level of liquid before and after after immersing an object into a graduated cylinder or beaker of liquid. For a small object immersed in a graduated cylinder or beaker, the volume displaced by the object can be read directly from the scale on the container.

You were asked to measure 5ml of water which one will you use - a 10ml or 100ml graduated cylinder?
You need to buy a desk that will fit in a very small space. Before you shop, would you use a measurement tool just estimate the space? Explain.How could you use a 100-ml graduated cylinder to measure 100mL?What two tools are used to measure length? When would you use each one?
What are you finding if you measure the space that a solid figure occupies?
You are finding the volume of the solid figure.To find the volume of a solid figure, depending on the size of the object, you can use a graduated cylinder. You can fill the cylinder up to x amount of water and then measure the amount after dropping the solid into the water, and then subtract the amount before, from the amount after, to get the volume of a solid. You can also use simple mathematics to figure the volume of the solid. There are different formulas for calculating volume for different types of solid figures.
If you have a graduated cylinder that contains ml of water you drop a rock into the cylinder and the water level rises to ml the mass of the rock is grams what is the rocks density?
density = mass/volume → The density of the rock is the mass of the rock divided by the difference in the volume from before the rock was dropped in and afterwards. Its units are grams/ml
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.
Where did president Joseph Estrada study?
Ejercito graduated from elementery at the Ateneo de Manila in 1951. He was later expelled from high school at the same institution for disciplinary reasons. He pursued coollege education at the Mapua Institute of Technology before dropping out of school altogether. Dropping out of college and involvement in a street gang so displeased his family that they forbade him from using his family name.
