Question

The volume of irregular solids like pebbles and stones can be determined using ___________.

• A. standard formulae
• B. water displacement method
• C. hydrometer
• D. lactometer

Answer 1

The correct option is B

water displacement method

B: water displacement method
1. This method is used to determine the volume of irregular-shaped solids.
2. This measurement can be done with the help of a measuring cylinder and eureka can.
A: standard formulae
With the help of standard formulae, we can only determine the volume of regular shaped solids.
C: hydrometer
This instrument is used for measuring the relative density of liquids.
D: lactometer
It is used for testing the purity of milk by measuring its density.
Thus, the volume of irregular solids like pebbles and stones can be determined using the water displacement method.

Hence, option (B) is correct.
