Formation of manure from leaves is a physical change?
Farmyard manure creates heat energy from decomposition of leaves. There is also physical change because the leaves' structure is broken down. The main factors for producing good manure are: water, which is already part of the manure; heat, which is generated by the decomposing leaves; and air, which is needed to aid the decomposition, because decomposition is a very slow form of "burning". Quite a high temperature can be generated in a manure heap or a compost heap.
