While conducting the experiment to measure the weight of water displaced by the body precaution should be taken to immerse the solid in water without touching the walls or bottom of the container. Why?
The sides and/or bottom could support the body, causing it to displace less water.

Precautions should be taken to immerse the solid in water without touching the walls or bottom of the container because it allows for accurate measurement of the weight of water displaced by the solid.
When a solid is immersed in a fluid (in this case, water), it experiences an upward buoyant force equal to the weight of the fluid it displaces, known as Archimedes' principle. By measuring the weight of the water displaced, we can determine the weight of the solid itself.
If the solid touches the walls or bottom of the container, it can affect the accuracy of the measurement in several ways:
1. Error due to adhesion: When the solid is in contact with the walls or bottom, there may be adhesion forces at play. These forces can cause the solid to stick to the container, leading to an inaccurate reading of the weight of water displaced.
2. Error due to additional displacement: Touching the walls or bottom can cause additional water displacement that is not caused by the solid. This extra displacement would be incorrectly attributed to the solid, resulting in an inflated measurement.
3. Error due to disturbances: If the solid touches the walls or bottom, it can cause disturbances or ripples in the water, which can affect the level and consistency of the water surface. This can lead to errors in measurement, particularly when trying to carefully determine the water level.
Therefore, to obtain precise and accurate results, it is important to ensure that the solid being measured does not touch the walls or bottom of the container while immersed in water. This can be achieved by carefully suspending the solid in the water using a string or support mechanism, ensuring that it is completely isolated from the container's surfaces.
