Question

it is difficult to burn a heap of green leaves but dry leaves catch fire easily . Explain ​

Answer 1

Answer:

Green leaves have a lot of chlorophyll and moisture in them. This moisture does not allow them to catch fire easily when a heap of green leaves are burnt. However, dry leaves have no moisture or water content in them. Therefore, the heap of dry leaves catch fire easily.

Answer 2

Answer:

A heap of green leaves contains a lot of moisture in it, hence its ignition temperature is high. Therefore, it does not catch fire easily.

But dry leaves have no moisture content in it, hence its ignition temperature is low. Therefore, it catches fire easily.
