Question

Which of the following is necessarily required to measure the density of irregular immiscible solids?

• A. Spring balance
• B. Measuring cylinder
• C. Water
• D. Pipette

Answer 1

Answer: (A), (B), (C)

The correct options are
A Spring balance
B Measuring cylinder
C Water

A measuring cylinder and water can be used to measure the volume of irregular solids. Following steps are involved in the measurement:

• Fill the measuring cylinder partially with water and note the water level.
• The solid is completely dipped in water so that the water level rises.
• The difference in the water levels in the two cases gives the volume of the irregular solid.

A spring balance is used to find out the mass of a body.

Once mass and volume of the solid are obtained, density can be found using the formula:
$\text{Density}=\frac{\text{Mass}}{\text{Volume}}$
