Detailed explanation-1: -The steam engine helped to power the Industrial Revolution. 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.
Detailed explanation-2: -They were powered by air pressure pushing a piston into the partial vacuum generated by condensing steam, instead of the pressure of expanding steam. The engine cylinders had to be large because the only usable force acting on them was atmospheric pressure.
Detailed explanation-3: -In a steam engine, burning fuel boils water to make steam, which pushes a piston, turning the steam’s thermal energy to mechanical energy. That mechanical energy can be used in a machine.
Detailed explanation-4: -The industrial use of steam power started with Thomas Savery in 1698. He constructed and patented in London the first engine, which he called the “Miner’s Friend” since he intended it to pump water from mines.
