Question

Match List-I with List-II.

List-I	List-II
A. Conduction	I. Heat transfer by bulk fluid movement
B. Convection	II. Heat transfer through a medium without mass flow
C. Radiation	III. Heat transfer by electromagnetic waves
D. Evaporation	IV. Heat removal by phase change

Choose the correct answer from the options given below:

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

Hint:

Conduction = no motion, Convection = fluid motion, Radiation = waves.

Answer 1

The Correct Option is A

Concept: Heat transfer occurs by three primary modes along with phase change processes.

Step 1: Conduction (A).

• Heat transfer without bulk motion So, A $\rightarrow$ II.

Step 2: Convection (B).

• Heat transfer by movement of fluid So, B $\rightarrow$ I.

Step 3: Radiation (C).

• Transfer through electromagnetic waves So, C $\rightarrow$ III.

Step 4: Evaporation (D).

• Heat removal via phase change (liquid to vapor) So, D $\rightarrow$ IV.

Step 5: Final matching. \[ A-II,\; B-I,\; C-III,\; D-IV \] Final Conclusion:
Option (1) is correct.
