Question

Which of the following is not a characteristic of fluids?

• A. They have a definite shape.
• B. They are compressible.
• C. They have mass.
• D. They can flow.

Answer 1

The correct option is A They have a definite shape.

Fluids (liquids and gases) are substances that have the tendency to flow. They don't have a fixed shape and can take the shape of the container in which they are filled. However, they have a definite mass and volume.

They have large interparticle space. When they are compressed, the particles moves closer to each other. Hence, they are compressible.
