 Why dry leaves burn easily than wet leaves?


  Let's get straight into it...

  It is because of ignition temperature. Ignition temperature is the lowest temperature at which a combustible substance starts burning. Now, green leaves have moisture or water in them. 

  Water has a property of absorbing a huge amount of heat before evaporating. Hence, when we try to burn green leaves, a large amount of heat is required to first evaporate the water and then to reach the ignition temperature of leaves, thus not allowing the leaves to catch fire easily.

  However, dry leaves don't have water in them. This, they don't need much heat, making them burn easily.
