Question

Match List-I with List-II.

List-I (Theory Proposed/Characteristic)	List-II (Thinker/Name of Theory, etc.)
(A) Saturated flow in soil	(I) Wien's law
(B) Soil textural analysis	(II) Darcy's law
(C) Wavelength of emitted radiation–temperature relation	(III) Fick's law
(D) Diffusive flux of gas	(IV) Stokes law

Choose the correct answer from the options given below.

• A. (A)-(I), (B)-(II), (C)-(III), (D)-(IV)
• B. (A)-(II), (B)-(I), (C)-(III), (D)-(IV)
• C. (A)-(II), (B)-(IV), (C)-(I), (D)-(III)
• D. (A)-(III), (B)-(IV), (C)-(I), (D)-(II)

Hint:

Remember the core transport equations:
- Water flow $\rightarrow$ Darcy's Law
- Particle settling $\rightarrow$ Stokes' Law
- Gas diffusion $\rightarrow$ Fick's Law

Answer 1

The Correct Option is C
