Question

The density of which of the following cannot be measured accurately using a spring balance and measuring cylinder and why?:
a) A ball filled with a liquid which is dropping out slowly
b) A block of ice
c) A small porous solid
d) All of the above

Answer 1

Answer:

d] all of the above

Explanation:

as for you now the object should be rigid, highly incompressible and complete solid with no interparticle spaces

Answer 2

The correct answer is option (c) A small porous solid.

Explanation:

• The density of A small porous solid cannot be measured accurately using a spring balance and measuring cylinder.
• It occupies a large volume and mass.
• It is said to be equal to the product of density and volume.
• The object should be rigid, highly incompressible and complete solid with no interparticle spaces.
• Hence, the correct answer is option (c) i.e A small porous solid.
