Question

Is air compressible? Give reason to support your answer​

Answer 1

Answer:

Gases are highly compressible to large vacant spaces between the molecules of a gas. As a result, its intermolecular force of attraction is less, and it has more distance between the molecules. Therefore, it is simple to compress the gas. Hence, the air has maximum compressibility.

Answer 2

Answer:

For air, when flow velocity is 100 m/s or less, the air is treated as an incompressible fluid, and when the velocity is greater than 100 m/s, the air is treated as compressible fluid. ... However, because an ideal fluid is easy to handle theoretically, it plays an important role for the basics of fluid dynamics.
