Question

Which of the below mentioned options is a set of solid objects?

• A. Rubber band, sugar, sponge
• B. Sugar, milk, sponge
• C. Rubber band, milk, sponge
• D. Milk, sponge, soap foam

Answer 1

The correct option is A Rubber band, sugar, sponge

Solids have a definite shape and volume. Rubber band, sugar and sponge, all are solids.

$\bullet$ A rubber band changes shape under force and regains the same shape when the force is removed.

$\bullet$ The shape of each individual, sugar or salt crystal remains fixed no matter which container it is taken in.

$\bullet$ A sponge has minute holes, in which air is trapped. When we press it, the air is expelled out and it will be compressed into a definite shape and volume.

$\bullet$ Milk is liquid and soap foam is gas trapped in liquid. Both do not have their own shape. They take the shape of the container they are kept in and hence are not solids.
