उत्तर
Measurement of volume of an irregular solid soluble in water using a graduated cylinder.
(a). In this case, kerosene or any liquid whose density is lighter than water and in which the solid is not soluble is used.
(b). Fill the graduated cylinder with the liquid.
(c). Record the lower meniscus of liquid and let the value be V1.
(d). Tie the solid whose volume is to be measured to a strong string and lower it into the water gently.
(e). Note the reading carefully and let the value be V2
(f). The volume of the solid, V = V2 - V1
