How do you find the volume of a marble?
There are several methods:From geometry and the formula for the volume of a sphere:Assuming the marble is a perfect sphere, the radius of the marble is one-half of the diameter, or width of the marble. Use the formula for volume,V = (4/3) pi r3where pi is approximately 3.1416 and can usually be found on a scientific calculator. R is the radius as mentioned before. The formula in text is "four-thirds times pi times the radius cubed." Make sure to do the cubing first.From the displacement the marble causes in water or other liquidyou can measure the volume of a marble by filling up a glass beaker to whatever amount you'd like,then you would see how much the water went up.and that would be you answerFrom the density of the marbleWeigh the marble and determine typical density of glass from available tables. As the density of the marble is found by the formulaDensity=mass/volume,divide the mass in grams by the density in gm/cm3 to determine the volume in cm3.
How can you determine the luster of the mineral marble?
Marble is actually a rock, not a mineral.
Explain how you find the volume of a marble using displacement?
You take a graduated cylinder,or anything you can measure water in, and put water in it. You drop the marble in and the change in water height is your volume. For example if the cylinder is filled up to 10ml and after you drop in the marble it goes to 15ml then the marble has a volume of 5ml cubed.
Does the rock have lower density than a marble?
the rock has a greater volume than the marble
How could you determine the densities of two different fluids without mixing them together?
1) determine the density of the first fluid 2) determine the density of the second fluid step 1) and step 2) are easy. just measure the volume and the mass and use the formula: "density = mass/volume" you can also... ~put the liquids in beakers (same amount in both) ~get a little marble ~drop the marble in one of the beakers ~use a timer to time how long it takes the marble to reach the bottom. ~take the marble out or if you have another marble use that ~drop the marble into the second fluid ~time how long it takes to reach the bottom ~the fluid with the less time should be the one that is denser ( you don't have to use marbles, you can use any other two object that are and weight the same).
What other methods besides the water displacement method can you use to determine the density of a marble and a wire?
Water displacement, in and of itself, cannot be used to determine density. Density is defined as mass divided by volume. Water displacement determines only the volume part of density. Whatever method you use to determine volume, you still need to determine the mass of the item before you can calculate its density. That said, another way to determine the volume of an object is to measure its dimensions and apply the appropriate formula. A wire can be considered a cylinder. A very long and very thin cylinder, but a cylinder nonetheless. The formula for the volume of a cylinder is: V = lπr2 where l is the length of the cylinder, π is "pi", the ratio of a circle's circumference to its diamater, approximately 3.14159, and r is the radius of the cylinder, or half of its diameter. Simply use a ruler to measure the length of your wire. If it is bent, twisted, or kinked, you will need to straighten it out first. Instead of measuring the wire's radius, you should measure its diameter and divide by 2. Unless your wire is thick, it may be difficult to get an accurate measurement of its diameter, even in millimeter units. Instead, you might try cutting the wire into ten pieces and laying them all side by side, touching each other, then measure the total width of all then pieces, then divide by 20 to determine the radius of your wire. It is important that you use the same units for both length and radius of your wire. Once you have determined the length and radius of your wire, square the radius, then multiply it by 3.14159 (π), then multiply it by the length of the wire. That is your volume. If you measured your length and radius in millimeters, the volume will in cubic millimeters. A million cubic millimeters is equal to one liter, so if "liters" is the unit in the denominator of your density measurement, you will need to divide your "cubic millimeters" volume by 1,000,000 before computing density. A marble is a sphere. The volume of a sphere is determined by the formula: V = 4πr3/3 or V = πd3/6 where d is the diameter of the marble. To determine the diameter of your marble, place it on top of your ruler with the left side even with the zero mark, then measure where the right edge falls on your ruler. Again, this may not be very precise. Alternatively, you could make a mark on your marble, then place your marble on the ruler with the left edge at the zero mark and the mark in the exact center of the marble as viewed from above. Then roll the marble, one complete revolution, along the ruler, until the mark is again in the exact center, then measure where the left edge of the marble is again. This is the circumference of your marble. To determine its diameter, just divide by pi (3.14159). To determine the volume of your marble, multiply the diameter by itself, then by itself again (d x d x d, or d3), then multiply by pi (3.14159), then divide by six. This is the volume of your marble. If your diameter measurement was in millimeters, the volume will be in cubic millimeters.
How do you measure the marble?
What do you want to measure about the marble? Its diameter, radius, circumference, volume, mass, density...?
What makes a marble rare?
The texture,materials,age, and size/weight determine the rarity of a marble
If marble has the mass of 132.796g the volume of 26.9cm3 what would be the density?
The density of the marble is about 4.94 g/cm3
When a marble is dropped in a bucket of water it sinks to the bottom. Is it because the marble weighs more than an equivalent volume of the water or the marble has greater mass volume than the water O?
All of the above? You can say the same thing in many ways. All of the following are different ways of saying the same thing, and all are correct: The marble sinks because the marble weighs more that an equivalent volume of water. The marble sinks because its density is greater than the density of water. The marble sinks because it has a greater mass than than same volume of water (and there is gravity/acceleration).
What is the best way to find the volume of a steel marble?
drop the marble in water and then see how much the water went up
What would you do to determine the volume of a rock?
You would determine the volume of water it displaces and measure it.
