Plant growth is both a chemical and mechanical process. The roots secrete mild acids that dissolve minerals in rocks, and the plant's roots and stems can increase in size and force rocks apart inside cracks and crevices.
Animals can cause both mechanical and chemical weathering of rock. The actions of walking, scratching, clawing, digging, tunneling, and scurrying about are enough to cause the breaking of rock into smaller particles (mechanical weathering), and the secretions and waste of some will cause chemical weathering. Most weathering caused by animals, however, is mechanical.
Caves are formed by both chemical and mechanical weathering. Most caves are formed by dissolution of limestone, however, which is a form of chemical weathering.

Rushing water is a physical phenomenon caused by the movement of water, and it is not related to mechanical, chemical, or nuclear processes. It is the result of the kinetic energy generated by the flow of water.
Coal is a chemical compound which contains chemical energy. To convert coal into mechanical energy, you use it (burn it) to produce heat and use the heat to boil water, the steam from which will drive a steam engine which delivers mechanical energy.

No, chemical because it involves water and water is a subject of Chemical Weathering not Mechanical.

I'm not sure if the act of letting water into wood, or a rock would fall under either chemical or mechanical. Probably more on the mechanical side.However, if the water freezes, thaws, and refreezes, then mechanical degradation can happen to the wood or stone.
The large intestine is mechanical digestion; it absorbs water and is involved in peristalsis. It has nothing to do with enzymes, which is chemical digestion.
Mechanical and chemical purification.
I Believe it is chemical weathering because oxidation is chemical and involves oxygen and water
