The rock's volume is simply the amount of water the rock displaced (52mL - 32mL), so 20mL.
The density is mass over volume, so 40g/20mL, which simplifies to 2 g/mL:
40 divided by 20 is 2, and then the unit is just mass (g) over volume (mL).
displacement - invented by Archimedes. Completely fill a large volume of something with water. Have a spout to channel all excess water. Place a graduated cylinder under the spout. Place irregular object in the large volume filled with water. The volume of the irregular object will displace an equivalent volume of water into the graduated cylinder. The measured volume in the cylinder is the volume of the irregular object.
stop cheating on gizmos, fool. :)The Answer: The mass of the water in the graduated cylinder is equal to the mass of the object.lol
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.
You can use a graduated cylinder to measure an object's volume.Fill the cylinder with water up to some convenient mark that's deeper than the object, and notethe volume of water in the cylinder. Than immerse the object in the water in the cylinder and notethe volume again. The difference between the two volume readings is the volume of the object.In my house, we have graduated cylinders which we refer to as our "measuring cups".
If the object in question is water proof, and small enough. You can measure the amount of displaced water when it is placed in a tank full of water, this may not work for a lot of things but it can help when attempting to measure some objects.
5 ml. Just do the volume after minus the volume before. This is the water displacement method.
To find the volume of an irregular object using a graduated cylinder, you can use the method of water displacement. Fill the graduated cylinder with a known volume of water, then carefully submerge the irregular object in the water. The increase in water level corresponds to the volume of the object. Subtract the initial volume from the final volume to determine the volume of the irregular object.
A graduated cylinder is used to measure the volume, or capacity of water. Or to just measure Water.
65 - 40 = 25 ml

You can put water in the graduated cylinder and drop the solid in and see how much the water rises
Use a graduated cylinder and the water displacement method. Pour the sample of water in the graduated cylinder and find its meniscus. That is its volume.

The unit of measurement that a graduated cylinder uses is the volume/mass of water.
Fill the graduated cylinder with water, and measure the volume. Now put the item in, measure the water's volume again, and take the difference

not quite. you can measure volume in a graduated cylinder. you can use a scale, water, and a graduated cylinder to find out the density of an object by filling the graduated cylinder to an easily calculated point (250) then dropping your object in the water making sure none splashes out then measure the difference, then weigh it and divide the mass by volume to get density.
