A perfect gas

Answer & Solution
Correct Answer: Option C
A perfect gas is an idealized concept used in fluid mechanics and thermodynamics to simplify analysis.

It strictly follows the ideal gas laws and assumes conditions such as no intermolecular forces and perfect elasticity of molecules.

In reality, no gas satisfies all these assumptions, so a perfect gas is not incompressible and does not have constant viscosity under all conditions.

Therefore, a perfect gas is mainly of theoretical interest, making option C the correct answer.

A theoretical model with no intermolecular forces and point-sized molecules.Obeys the ideal gas law (PV=nRT).Molecules have random motion and elastic collisions.It's a compressible fluid, not an incompressible one.
