Is burning coal reversible or irreversible?
irreversable
Is burning coal a reversible change?
No, for coal burning to be a reversible change, you would need the ability to take CO2 and turn it back into solid carbon.
Why is burning of coal a chemical change?
Because it is irreversible(we cannot get the coal again) and totally new products are formed i the process
Is burning coal for a barbecue physical or chemical change?
burning of coal is chemical change
Is burning of coal a chemical change?
Yes. The coal is a solid which than burningthe coal makes a gas.

How come world thermodynamicists fail to recognize that what makes coal combustion the energy of choice for electricity is the reversible piston turbine reversible process?
I am not sure what you mean. What process is that? Any combustible fuel will work, not just coal. You can read about the thermodynamics part by looking for a description of the "Carnot engine". The process is NOT reversible; although the Carnot engine is reversible in theory, there are always losses in practice that make it irreversible; also, the fact of burning the coal is not reversible.

Is burning coal for a barbecue a physical change?
No, it is a chemical change
Is burning coal a physical change?
No. Burning anything is a chemical change.
Is Burning coal physical or chemical change?
Burning coal is a chemical change. Anytime heat is released (as such in fire) it will be a chemical property change.
Is burning coal in a furnace a chemical change?
Burning is a chemical change, an oxidation.
Is burning wood into charcoal a physical change?
Unfortunately, it is not a physical/reversible change, as combustion causes chemicals to change their bonding. A simpler example than wood would be glucose (the same reaction as in respiration): C6H12O6 + 6O2 --> 6CO2 + 6H2O This reaction is not reversible.
