It really depends HOW the conversion is done. The usual process is to burn the coal; if this is done, the next step is to use a heat engine, and the efficiency of a heat engine is limited in theory by the Carnot efficiency. Of course, in practice, heat engines will be even less efficient than the theoretical Carnot engine.However, if you could find a practical way to use the fuel directly in a chemical reaction (basically, a fuel cell), the resulting efficiency could be much higher.
Because it is
photosynthesis
A simple answer is that fossil fuels are burnt. The heat is used to produce steam which drives mechanical turbines and dynamos, which then produce electricity.
The process of converting waste to reusable material is called recycling.
No. It is a physical process. Chemical weathering is a chemical process.
electrolysis electro is electrical power lysis is latin for breakdown
No. You must not confuse the PROCESS of converting some chemical products to others, with the RESULT. The PROCESS of converting wood and oxygen to smoke is a chemical change. The SMOKE itself is not.
No.

the process is called evaporation
Chemical energy is converted into electrical energy.

The process of charging a storage battery.
Amyglucosidase is a carbohydrase chemical that is converting starch to become fermentable carbohydrates. This chemical was discovered through a repeated process of wine making throughout the years.
