Water Displacement
displace it
Displacement method.... Is the method to find volume of an irregular object
Either: 1) Find the radius of each marble and thus their volume through V = 4/3 x pi x r^3 and then add the volumes up. or 2) Put all the marbles in a measuring jug and fill it up to the top. Pour the water into a separate container and empty the marbles out of the jug. Pour the water back into the jug. Thus: Volume of water with marbles - volume of water without the marbles = volume of marbles
We don't know what size marbles you have, so we can't tell you their volume.But we can tell you that you had better get the same answer no matter whatmethod you use, otherwise something is definitely fishy. The answer never dependson what method you use to find it.
You fill your displacement cup with water until the hole is finished dripping. Then, you're going to add the four marbles that you asked for. But before you add the marbles inside the displacement cup, you must place a graduated cylinder under the hole in the displacement cup so you can find the volume of a marble. When you discover your results, divide how much water is in the graduated cylinder by the number of marbles you inserted. In this case, it would four.
To find the density of marbles, you would measure the mass of a certain number of marbles using a balance scale, then calculate the volume by either measuring the dimensions and using a formula for the shape of the marbles or by displacement method with water. Finally, divide the mass by the volume to determine the density of the marbles.
Use a scale to find the mass of several marbles. Put some water in a graduated cylinder. Take a reading. Place all the marbles in the grad. cylinder with the water, which will rise. Take another reading. Make sure the marbles are completely submerged. Subtract the 2 readings. This gives the volume of the marbles. This is called the water displacement method. Divide mass by volume. This gives you the density.
Water Displacement
Yes, water displacement can be used to find the volume of solid objects that do not dissolve in water. By measuring the change in water level before and after submerging the object, you can calculate its volume based on the amount of water displaced.
