Steam engines use hot steam from boiling water to drive a piston (or pistons) back and forth. The movement of the piston was then used to power a machine or turn a wheel. To create the steam, most steam engines heated the water by burning coal.
Step-by-step explanation:
your first question is boiling water
second question is Before steam power, most factories and mills were powered by water, wind, horse, or man. Water was a good source of power, but factories had to be located near a river.
the last one is While the Spaniard first patented a steam-operated machine for use in mining, an Englishman is usually credited with inventing the first steam engine. In 1698, Thomas Savery, an engineer and inventor, patented a machine that could effectively draw water from flooded mines using steam pressure.
