Question

Which of the following is a set of solid objects?

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

Answer 1

The correct option is A

Rubber band, sugar, sponge

A rubber band changes shape under force and regains the same shape when the force is removed. If excessive force is applied, it breaks. The shape of each individual sugar or salt crystal remains fixed; whether we take it in our hands, put it on a plate or in a jar. 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. Milk is a liquid and takes the shape of its container. Foam also behaves the same way.
