Question

How does a steam engine do work?
(a) Steam turns a turbine.
(b) Steam enters a cylinder and pushes a piston.
(c) Steam expands and spins an axle.
(d) Steam causes wheels to turn.

Answer 1

as water is heated up, it turns to steam

steam expands and enters a cylinder

a piston is pushed by the expanding steam in the cylinder
this action is the steam doing work on the piston

the motion of the piston is translated into a rotation motion, which can then be used to drive stuff

Answer 2

In a steam engine, the steam enters a cylinder and pushes a piston.

How does a steam engine work?

When the engine is heated, the water converts into the invisible vapor, that is, steam. This formation of steam, results in high pressure. The expansion of the steam pushes the pistons. The passing of the steam takes place to the piston valves, which monitor the admission of steam to the cylinders.

At the termination of the piston stroke, an exhaust port opens, which permits the steam to escape. After this the process is reversed and is repeated in the reverse direction. The entry of steam takes place to either side of the piston. The pistons pull or push the rods associated with the drive wheels, giving the force required to move the locomotive.

Thus, the correct statement is option b.
