Hi friend!
In picture A, the substance undergoes incomplete combustion while in picture B, no combustion takes place due to the absence of air.
Reason:
This is because, in the first case, the substance gets a lot of air for combustion while in the second case, as the wood is covered with clay, combustion is difficult due to the absence of air.
Hope it helps you!!!
