Question

Match the entries in Column I with the correct entries in Column II. 

• A. P-(iii), Q-(ii), R-(i)
• B. P-(ii), Q-(i), R-(iii)
• C. P-(i), Q-(iii), R-(ii)
• D. P-(ii), Q-(iii), R-(i)

Hint:

In matching questions, ensure you understand the key concepts behind each term to correctly associate them with their definitions or laws.

Answer 1

The Correct Option is D

Let’s match the terms from Column I to Column II based on their respective relationships:
P. Diffusion: Diffusion is governed by Fick's law, which relates the rate of diffusion to the concentration gradient. Therefore, P matches with (ii) Fick.
Q. Drag force: Drag force is described by Stokes' law for particles moving through a fluid. Hence, Q matches with (iii) Stokes.
R. Atmospheric stability: Atmospheric stability is a term used in Pasquill's stability classes to categorize the degree of turbulence in the atmosphere, so R matches with (i) Pasquill.
Thus, the correct matching is P-(ii), Q-(iii), R-(i).
Final Answer: \[ \boxed{\text{(D) P-(ii), Q-(iii), R-(i)}}. \]
