I think I can explain this. We know it has to be a metal bowl so that it conducts the heat from the milk. Now, if we have a thinner bowl, the conducted heat can be transferred to the air faster and more efficiently. That's why I think the answer is c and not d.

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

No, it is A. R's liquid might absorb oxygen but how will it get CARBON DIOXIDE? So, R cannot be correct. P and W are both damp and both have air. If you read synopsis,seeds can sprout a little bit without sunlight. So, option A is correct.
