How would i measure the volume of a sponge?
You could first soak the sponge in water, then use the standard method of measuring irregular objects: fill a graduated cylinder with 100 mL of water, then drop in the wet sponge and see how much the water level rises.
How do you figure out the volume of an irregular solid since you cannot pour a solid into a graduated cylinder?
The easiest way to measure the amount of fluid it displaces. So if you fill a graduated cylinder with a certain amount of water, and then place the solid object inside the cylinder, the water level will increase. The amount of increase equals the solid objects mass. EUREKA!
What is a measuring cylinder used to for?
A graduated cylinder is used to measure the volume of a liquid and occasionally a solid (it can be inverted and used to measure gas as well!) The cylinder is made of glass (usually Pyrex) or plastic and has measured lines with volume values noted on the lines (a.k.a. graduations.) Simply fill the cylinder with a liquid until it reaches the volume you require. When measuring the liquid level you will notice that electrostatic forces and gravity alter the shape of the liquid's surface to a crescent shape. This is called a "meniscus." In most cases the shape will look like a smile, you must make the measurement so the bottom portion of the smile shape is lined up with the graduation mark on the cylinder. Occasionally the meniscus will be close to flat or inverted like a frown, such is the case with liquid mercury. In such scenarios, the uppermost portion of the frown shape should be used for accurate measurement. To measure the volume of a small solid object of irregular shape, you can measure out a certain volume of a liquid (like water) in the cylinder, and then carefully place the solid objects in the cylinder, making sure they are completely submerged and contain no air bubbles. The water is displaced to a new reading on the graduated cylinder and the difference between the original and the final readings is the volume that the solid object occupies. Measuring the volume of a gas is more complicated to set up and explain. In general the graduated cylinder is filled with liquid and inverted in a large container filled with water. The gas reaction evolves gas through a tube, directly under the inverted cylinder, and rises to the top (the base of the inverted cylinder). The amount of gas produced will displace the water downward as it fills the top of the cylinder and can be measured using the graduations when the gas has ceased. This will give you the volume that the gas occupies. If the gas is soluble in the liquid, some may remain dissolved and give a false-low volume reading.
How do you know which objects are more dense or less dense?
Density is weight divided by volume. Weight is measured with a scale. Volume can be calculated if an object has a regular shape, using basic geometry, but if it has an irregular shape, it can be calculated using a graduated cylinder.
What is parallax bar?
A parallax bar or stereometer is a simple measuring device that is used to determine the height of objects in photographs.
What is the use of graduated cylinder in laboratory?
the use of graduated cylinder is for measuring liquid objects
What is use of graduated cylinder?
A graduated cylinder is used for measuring the Volume of different things such as irregular objects. It uses the unit ml. It has a miniskus FYI that is when you use water and if you look closely you can see it curve at the top. You measure the miniskus a the bottom of the Curve. Also to find the Volume of an irregular object you first measure the water (starting volume) then place the Object in it and you will have your ending volume. then subtrct the difference from the starting volume and the ending and you will have your volume in ml.
What is an instrument used to measure volume of liquids and irregularly shaped objects?
graduated cylinder
Can you use a graduated cylinder to find which of two objects has a greater mass?
No, you would not use a graduated cylinder to compare the mass of two objects, that would be silly. Graduated cylinders are only useful to measure volume, not mass. Mass is measured with a scale. Chemists usually use a triple beam balance.
Why should you tilt a graduated cylinder when you drop objects in them?
Tilting a graduated cylinder when putting something it in is is so that the object will not break. If you just drop the object straight in it will go straight to the bottom and break.
Why should you tilt a graduated cylinder when you drop in objects?
Tilting a graduated cylinder when putting something it in is is so that the object will not break. If you just drop the object straight in it will go straight to the bottom and break.
What measure tool do you use to measure objects?
To measure the mass on an irregular object, you can use Water Displacement.Water displacement is a way of measuring mass. Materials needed for this are:A graduated cylinderWaterVariable (Irregular Object).Fill the graduated cylinder with a certain amount of water. Memorize it.Put the irregular object into the graduated cylinder. Find the mass by subtracting the first amount of water from the second. That's your mass.Hope this helps, and sorry if you didn't need all this information!

A graduated cylinder is usually calibrated in what?
A graduated cylinder is a piece of laboratory equipment used to accurately measure out volumes of objects for use in labs. They are generally more accurate and precise for this purpose than flasks and beakers.
What device is appropriate in measuring spherical objects?
calipers can measure its diameter and check for roundness. Water displacement can measure its volume.
What is the Function of the Measuring Cylinder?
A measuring cylinder also called graduated cylinder is laboratory glassware used to measure the volume of liquids. Some of its functions are the following: it is used at home when there is a need to measure volume of liquid ingredients required for a recipe and itÕs also used to accurately measure liquids used in chemistry or biology laboratories.
How do you find the weight of the equal volume of water that buoys up the immersed stone when it is immersed?
you can use a 300ml graduated cylinder water,3different objects
