Detailed explanation-1: -The coal-fired steam engine was in many respects the decisive technology of the Industrial Revolution. Steam power was first applied to pump water out of coal mines.

Detailed explanation-2: -The first useful steam engine was invented by Thomas Newcomen in 1712. The Newcomen engine was used to pump water out of mines. Steam power really took off with improvements made by James Watt in 1778.

Detailed explanation-3: -The steam engine, either used on its own or as part of a train, is the iconic invention of the industrial revolution. Experiments in the seventeenth century turned, by the middle of the nineteenth, into a technology which powered huge factories, allowed deeper mines and moved a transport network.

Detailed explanation-4: -The first steam engine used for work was patented by the Englishman Thomas Savery in 1698 and was used to pump water out of mine shafts. The basic process involved a cylinder that was filled with water. Steam was then delivered to the cylinder, displacing the water, which flowed out through a one-way valve.
