Fluid Properties MCQ with answer and solution

Concept

Compressibility of fluids

Step-by-step solution

1. Liquids are almost incompressible. 2. A gas such as helium is highly compressible, so it is the least incompressible.

Explanation

Gases compress easily; liquids have a high bulk modulus.

Why the other options are wrong

Gasoline, kerosene and water are liquids.

Shortcut

Gas = most compressible.
