Expert Answer:

1) Burning coal: Chemical energy is converted to heat energy.
 
2) moving car:  The car burns the petrol. Thus the chemical energy is converted to heat energy and then is converted to the mechanical energy(kinetic energy of moving car).
 
3) a gun shot: The pressing on trigger of the gun possesses potential energy. When it is shot the potential energy is converted to the kinetic energy of the bullet which is fired form the gun.
