Heat and water. Remember all those movies where trains shoveled coal into a furnace? It wasn't running on burning coal. What was actually happening was that the front of the engine was filled with a tank of water. The burning coal turned some of the water to steam, increasing the pressure in the tank. As the pressure increased, the steam was directed through valves to turn pistons, which turned wheels. A very simple design, but inefficient, because it took a lot of heat energy to create the kinetic (motion) energy.

The source of energy for a steam engine is heat energy from the steam which is converted into mechanical work that is used to push pistions and other mechanical devices.
Hope this helps.

Burning coal or wood. depnds on the era of the steam engine. Today they convert steam engines to use other, cleaner, sources like diesel oil, or natural gas. The heat is used to boil water and the steam is used to move the drive pistons that turn the drive wheels.

thats not a question
obviously steam is the source of energy in steam engine
look in steam engine water is at temperature far above its boiling point
the water is then converted into steam at its boiling point
the extra temperature provides the extra energy which steam possess in the form of kinetic energy
this kinetic energy is used to rotate the turbines and thats how steam engine works

at certain temperature water is going to boil if it is placed in an open system all the steam produce during boiling is exit that system if it is packed than thik makes a certain kind of preesure and by thinking on this theory our steam engines made and they work

water and heat..... the water is heated which forces it to rise and then turns wheels and gears in the machines engine which powers it and makes the craft move. this applies to boats..
steam trains build up pressure in their engine that make things turn to power it.

steam. produced in a sealed vessel full of water, add heat to produce steam.
