Why is the graduated cylinder used instead of a ruler to measure the volume of a rock?
Because most rocks are not made up of common geometric shapes, it would be difficult or impossible to find the volume of a rock using a ruler; there would be no easy way to measure the rock's irregular volume. However, by measuring the volume of liquid a rock displaces, its volume can easily be determined.
What do you do in order to measure the volume of rock?
Fill a beaker or measuring cylinder with water and record the volume of water indicated. Put the rock in the beaker/measuring cylinder and record the new volume of water indicated. The difference between the two volumes is the volume of the rock.
How do you find density of a rock?
The simplest way is to use the formula: P = m / V Density = mass / volume So to calculate the denisty of the rock you will have to find out how much it weighs and how much volume it occupies. You can measure the weight by placing the rock on a weighing scale, this will give the weight in grams. You can determine the volume by submerging the rock in a measuring cup partially filled with water and measuring how much the volume increases. This will give the volume in cm3 Now use the formula to calculate its density in g/cm3.
How can you find the volume of a rock that is too big to fit into a graduated cylinder?
One way to find the volume of a large rock is to use the water displacement method. Fill a container with a known volume of water, then carefully lower the rock into the water. Measure the change in water level to determine the volume of the rock.
What is the SI unit for measuring the volume of plastic rock?
cubic meter
How can you find the volume of a small rock using only water and either a measuring cup or a graduated cylinder?
Fill the cylinder with water to a marked point. Then place the rock in the water and measure how much the water level rises. That will give you the amount of volume displaced by the rock and so the volume of the rock.
What tool do you use to measure a rock?
If measuring weight - use a scaleIf measuring mass - use a balance in units of grams or kilograms.If measuring size (L x W x H) - Use a ruler/tape measureIf measuring volume - use a graduated cylinder.
How could you find the volume of a small rock using a graduated cylinder and water?
Fill the cylinder about half way with water and measure the amount. Then drop the rock in and measure the amount of water. Now subtract no rock from rock in and that will give you the amount of volume displaced from the rock.

However, by measuring the volume of liquid a rock displaces, its volume can easily be determined.
If you found a rock and you want to measure its volume what would you do to measure the rock volume?
Use water displacement. Measure water before you put the rock in it, and then again afterwards. Put a measuring cup large enough to hold the rock in a pot large enough to hold the measuring cup and fill the measuring cup to the very top with water. Lower the rock into the measuring cup carefully so that the water flows over and into the pot. Carefully remove the measuring cup with the rock without spilling any additional water into the pot. When you measure the water in the pot it will equal to the volume of the rock (accuracy will depend on how careful you were). This is displacement measuring.
How do you measure a irregular solid?
You use a graduated cylinder to measure the volume of the rock with the water and the water without the rock
What do you do in order to measure the volume of rock?
Fill a beaker or measuring cylinder with water and record the volume of water indicated. Put the rock in the beaker/measuring cylinder and record the new volume of water indicated. The difference between the two volumes is the volume of the rock.
What would you use to measure 10.5g of rock salt?
You could use a standard kitchen scale to measure out 10.5g of rock salt accurately. If you don't have a scale, you can estimate using measuring spoons, keeping in mind that 1 teaspoon of rock salt is approximately 6g.
How do you find the volume of n irregularly shaped rock?
use a graduated cylinder or other volume measuring container. just put a certain amount of water in, take note of it, then put the rock in and measure the difference, make sure the water goes up and above the rock though
Describe how a graduated cylinder could be used to measure the volume of a rock with an irrregular shape the process must include at least three steps?
Step 1 . calculate the volume of the cylinder step 2 . put the rock in the cylinder and fill it with water to the top step 3. measure the amount of water step 4 subtract the volume of the water from the volume of the cylinder, and you have the volume of the rock.
How can you figure out the density of a irregular rock?
To determine the density of an irregular rock, you can use the water displacement method. First, measure the initial volume of water in a graduated cylinder. Then, submerge the rock completely in the water and measure the new water level; the difference in volume indicates the rock's volume. Finally, divide the mass of the rock (measured using a scale) by the volume obtained from the water displacement to calculate the density.
Describe a method that the student could use to find the volume of this rock?
You can find the volume of a small rock in no time at all. Just fill up a container that is marked by volume with water and record the volume. Then drop the small rock inside the container. Record the new volume. Find the difference between the new and old volumes. This is the volume of the small rock. You could do this in any liquid.
