Observe the given figure carefully and choose the correct option for matching the column I with column II.

Column I    Column II
(A)X (i) The process of transfer of heat in a liquid or a gas by the movement of liquid or gas.
(B)Y (ii) The flow of heat through a substance without the movement of the substance itself.
(C)Z (iii) The process by which heat travels without the help of material medium.


A (A)-(iii), (B)-(i), (C)-(ii)
B (A)-(ii), (B)-(iii), (C)-(i)
C (A)-(i), (B)-(ii), (C)-(iii)
D (A)-(ii), (B)-(i), (C)-(iii)


Ans 1:

Class : Class 8
i think the answer is A as the process X is of radiation and process Y is convection and process Z is conduction . a medium is not required in radiation . convection takes place in fluids . that is why i think the answer is option A
