Problem: - Coal is loaded into the firebox - The boiler produces steam under high pressure - The steam generated in the boiler flows down into a cylinder - Just ahead of the wheels, pushing a tight-fitting plunger, the piston - The piston is connected to one or more of the locomotive's wheels through a kind of arm-elbow-shoulder joint called a crank and connecting rod - As the piston pushes, the crank and connecting rod turn the locomotive's wheels and power the train along What might be the last step of the process?

A: An outlet valve opens and the piston pushes the steam back through the cylinder and out up the locomotive's chimney
Problem: Given the question: - A type of coal must be chosen before the heating can start - The coal is broken down to a smaller material - The coal particles mix with hot air and move in to a boiler - Water in the boiler is pumped and produces steam with the coal - Steam powers turbine blades, which magnetically charge wire coals What might be the last step of the process?
