Density of an Irregular Solid

Aim: To determine the density of an irregular solid.

Apparatus: 

Measuring Cylinder

A Glass Stopper

Tissue Paper

String

Electronic beam balance

Scissors

Procedure:

1. Weigh the glass stopper to determine its mass. Record its mass as M.

2. Pour water into the measuring cylinder to one-third of the cylinder's height. Note the volume as V1.

3. Tie the glass stopper to a string and lower it gently into the water. Note the volume as V2.

4. The volume of the glass stopper is V2-V1. Record the volume of the glass stopper as V.

5. Remove the glass stopper and dry it with tissue paper.

6. Repeat step 2 twice with different values of V1 and obtain the corresponding values of V2 and V2-V1.

Find the average volume of the glass stopper from the 3 readings.
