Simply because the volume of water displaced is not equal to the actual volume of the object. If an object is lighter than water, you have to find another method of determining its volume.
------------------------------------
alternatively you could use a very thin pin to push the object under the water. However, the volume of the submerged portion of the pin would need to be suvtracted from the volume of the object measured.
Push it down to measure the volume.
To find the volume of something that floats, you can measure the amount of water it displaces when submerged. The volume of water displaced is equal to the volume of the object. This can be calculated by measuring the change in water level before and after submerging the object.
If possible, fully immerse the object in water, and measure the volume of displaced water.
To measure the volume of an irregular object that floats on water, you can use the water displacement method. Fill a container with a known volume of water, measure the initial water level, then place the object in the water and measure the new water level. The difference in water levels represents the volume of the object.
Push it down, and measure the displaced liquid.
Put the object in a measuring container; pour in water to cover the object and measure the volume in the container; take the object out of container and measure the volume remaining. The difference is the volume of the object. If the object floats push it down until covered with water.
To find the volume of an irregular object that floats in water using water displacement, you can follow these steps: Fill a container with a known volume of water. Measure the initial water level. Carefully lower the object into the water and measure the new water level. The difference in water levels before and after submerging the object is equal to the volume of the object.
Yes, the water displacement method can be used to calculate the density of an object that floats in water. To do this, you would need to measure the volume of the water displaced by the object when it is submerged, and then divide the object's mass by this volume to find its density.
To find the density of an object that floats, you can use the formula density = mass/volume. First, measure the mass of the object using a scale. Then, submerge the object in water and measure the volume of water displaced, which is equal to the volume of the object. Finally, divide the mass of the object by its volume to calculate the density.
To find the density of an object in water, first measure the mass of the object using a scale. Then, measure the volume of the water displaced by the object when it is submerged. Divide the mass of the object by the volume of water displaced to calculate the density of the object in water.
Yes, according to Archimedes' principle, when an object floats in a fluid, the weight of the object is equal to the weight of the fluid it displaces. This means that the volume of the displaced water is equal to the volume of the object.
You can push it under water / under the liquid's surface, and measure the displacement of liquid.
