# Can the water displacement method be used for all solids?

## Can the water displacement method be used for all solids?

Water displacement method to determine volume of a solid can’t be used for all solids. The reason for this is some solids will float on the water. Therefore the object’s density is less dense than the water.

Do you use the displacement method to find volume?

The displacement method (submersion, or dunking method) can be used to accurately measure the volume of the human body and other oddly shaped objects by measuring the volume of fluid displaced when the object is submerged, as illustrated in the figure below.

### Can you use water displacement to find volume?

Place the graduated cylinder upright on the table and look at the level of the water. Record the number of milliliters for this final water level. Find the amount of water displaced by subtracting the initial level of the water from the final level. This volume equals the volume of the cylinder in cm3.

Do you think that the water displacement method will work for measuring the volume of a tablespoon of sugar explain?

No, the water displacement method will not work for calculating the density of a tablespoon of sugar. This is because the sugar dissolves and becomes solvated (surrounded by) water molecules.

## Why displacement method is used for measuring the volume of an irregular solid?

Explanation: This is due to the fact that irregularly shaped objects can not be measured with a ruler. Water displacement is used. Depending on how much the water rise after the object has been placed inside the cylinder the volume can then be calculated.

Why is water displacement more accurate?

The change in water level equals the volume of the submerged object. This method is more accurate than measuring water that has spilled out an overflowing beaker. Using the smallest graduated cylinder possible allows for a more accurate measurement.

### Could you use the method of volume displacement to determine the volume of a piece of wood Why or why not?

Displacement method of volume measurement is no suitable for the objects that do not get immersed into the water completely because of the hindrance in accuracy of the measurement. Explanation: But when the object does not sinks below the surface of the water as in case of wood, coal, ice etc.

How does the water displacement method determine density?

The mass of atoms, their size, and how they are arranged determine the density of a substance. Density equals the mass of the object divided by its volume; D = m/v. Objects with the same mass but different volume have different densities. Students use the water displacement method to find the volume of different rods that all have the same mass.

## How is the volume of a solid determined?

The volume of a solid is the measure of how much space an object takes up. This article will show how to calculate the volume of a solid and the volume of regular and irregular solids. The method for determining the volume of solid depends on its shape.

How is the volume of water displaced equal to its volume?

The volume that the rod takes up pushes or displaces the water. The only place for the water to go is up. The amount or volume of water displaced is equal to the volume of the sample. Is the volume of the sample equal to the final water level?

### How to find the volume of an object using water?

Announce that they will find the volume of these objects using water and a method called water displacement. Engage students by having them do a displacement activity to see that 1 cm 3 = 1 mL. Further engage students in estimating the volume of objects by using water displacement.
