Question

How will you find the volume of an irregular solid (lighter than water) by displacement method?

Answer 1

Measurement of volume of an irregular solid Lighter than water by the displacement method
a. Fill the graduated cylinder with water.

b. Take a heavy solid (eg. piece of metal) insoluble in water. This metal piece is called the sinker.

c. Tie the sinker to a strong string and lower it into the water gently and record the lower meniscus of water and let the value be V₁.

d. Now take out the sinker and along with it tie the solid whose volume is to be measured and Iower them into the water.

e. Note the reading carefully and Iet the value be V₂

f. The volume of the solid, V = V₂ - V₁
