Question

Which of the following items does not flow ?

• A. Solid
• B. Liquid
• C. Gas
• D. Liquid and Gas

Answer 1

The correct option is A

Solid

Any material that can flow and needs a container to keep it is called fluid. For example- water, milk, and juices are fluids.

The explanation for the incorrect answer:

• The property of liquids and gases to flow is called fluidity. Due to the property of fluidity, fluids can change their shape by applying pressure.
• Cooking gas(LPG), and water are the two substances that possess the property of fluidity.

The explanation for the correct answer:

• The particles of the solids are tightly packed and hence they have a definite shape.
• There is a strong force of attraction between the particles. They cannot move but oscillate about their mean position.
• Hence they do not show fluidity.

Hence the correct option is A.
