Question

Match the following.
$$\begin{array}{cccc}& \text{Column 1}& & \text{Column 2}\\ A& \text{Compressible fluid}& i& \text{Internal friction between adjacent layers is absent}\\ B& \text{Incompressible fluid}& ii& \text{Has variable density}\\ C& \text{Viscous fluid}& iii& \text{Internal friction between adjacent layers is present}\\ D& \text{Non-viscous fluid}& iv& \text{Has constant density}\end{array}$$

• A. $A\to \left(ii\right);B\to \left(iv\right);C\to \left(iii\right);D\to \left(i\right)$
• B. $A\to \left(iv\right);B\to \left(ii\right);C\to \left(iii\right);D\to \left(i\right)$
• C. $A\to \left(ii\right);B\to \left(i\right);C\to \left(iv\right);D\to \left(iii\right)$
• D. $A\to \left(iii\right);B\to \left(iv\right);C\to \left(i\right);D\to \left(ii\right)$

Answer 1

The correct option is A $A\to \left(ii\right);B\to \left(iv\right);C\to \left(iii\right);D\to \left(i\right)$

Compressible fluid has variable density.
Incompressible fluid has constant density.
In viscous fluid, internal friction between layers is present.
In non-viscous fluid, internal friction between layers is absent.
