When it comes to measuring the volume of irregularly shaped objects, the displacement method is often used. This method involves submerging the object in a liquid and measuring the volume of liquid displaced. In this article, we will explore the displacement method in detail, discuss its advantages and disadvantages, and compare it to other volume measurement techniques.
What is the Displacement Method?
The displacement method is a technique used to measure the volume of irregularly shaped objects. Unlike regular solids, irregular objects do not have a simple formula to calculate their volume. As a result, the displacement method provides an effective way to determine their volume accurately.
In this method, a graduated cylinder is filled with a liquid, typically water, to a certain level. The object whose volume needs to be measured is then carefully submerged in the liquid, causing the liquid to be displaced. The volume of liquid displaced is equal to the volume of the object.
Advantages of the Displacement Method
The displacement method offers several advantages:
- Quick and Easy: The displacement method is a fast and simple way to measure the volume of irregularly shaped objects. With the appropriate liquid and object, the process is straightforward and efficient.
Disadvantages of the Displacement Method
Despite its advantages, the displacement method does have a few drawbacks:
- Reaction with the Liquid: Certain objects may react with the liquid used, which can affect the accuracy of the results. Some objects may even dissolve slightly, leading to inaccurate volume measurements.
- Water Suction: The string used to lower the object into the water may suction some water, causing discrepancies in the measurements.
- Object Floatation: If the object being measured is too light, it may float on the water, leading to inaccurate volume calculations.
Despite these disadvantages, the displacement method is still a commonly used technique due to its simplicity and effectiveness.
Comparison to Other Volume Measurement Techniques
Another commonly used technique for measuring volume is using a measuring cup or graduated cylinder. This method is suitable for measuring the volume of liquids, but it is not ideal for irregularly shaped objects.
The displacement method provides a more accurate measurement for irregular objects as it takes into account their unique shapes. By submerging the objects in a liquid, any irregularities or void spaces are accounted for in the volume measurement.
It’s also important to note that the volume of gases depends on the volume of their container, and the volume of regularly shaped solids can be calculated using their dimensions.

Frequently Asked Questions
How To Find Volume Using The Displacement Method?
To find the volume using the displacement method, follow these steps: 1. Take a graduated cylinder and fill it with a known volume of liquid. 2. Gently lower the object into the graduated cylinder, making sure that it is completely submerged.
3. The volume of the liquid will increase due to the displacement caused by the object. 4. Read the new volume on the graduated cylinder. 5. Calculate the difference between the initial and final volume to find the volume of the object.
What Is The Volumetric Displacement Method?
The volumetric displacement method measures the volume of irregularly shaped objects by submerging them in liquid.
What Is The Formula For Volume Displaced?
The formula for volume displaced is found by submerging the object in a liquid, and measuring the amount of liquid displaced.
What Are The Two Methods To Measure Volume?
Two methods to measure volume are by using the displacement method or a measuring container.
Conclusion
The displacement method is a widely used technique for measuring the volume of irregularly shaped objects. By submerging the object in a liquid and measuring the volume of liquid displaced, accurate volume measurements can be obtained.
While the displacement method has its advantages and disadvantages, its overall effectiveness, speed, and simplicity make it a popular choice in scientific experiments and everyday applications.
