How did coal/steam change the world

The machines are called steam engines, which, with external combustion engines, work to convert the thermal energy (the force of heat) of the boiling water into mechanical energy.

The heat resulting from the burning of certain amounts of coal boils the water that turns into steam. That steam is captured and directed to feed a series of elements that start the machine.

Thomas Newcomen invented the steam engine in 1705. With the help of colleagues such as physicist Robert Hooke and mechanic John Calley, Newcomen was the first to make a steam engine proper.

Some years later it was used as a basis for several of the most important inventions of the Industrial Revolution, such as the locomotive, steam ships and factories, among other things.

The steam engine and coal revolutionized production in the factories, both objects were one of the drivers of the industrial revolution.

explanation: we can only guess at how our actions may be perceived in the future. doing something really big like killing lots of people, saving lots of people, affecting the lives of lots of people is a sure fire way of being remembered in historical records. we can also make a difference in the history records by being a small influence on something bigger, whether that is as a civil servant, scientist or artist.

of course you could argue that we all affect history just as tiny cogs in a   bigger machine.

if you mean how do people influence our opinions of things which have already happened, then simply by writing a book which looks at things form a different perspective and trying to convince people that this perspective is more accurate or truthful. people do it all the time i.e. richard the third was a terrible or was he? plenty would disagree, it's just that their views aren't the most widely known.n:

the phenomenon that would be cited as evidence of increased economic interdependence between europe and the americas is  the development of mercantilism.

this theory suggests that the wealth of a country depends on its economic assets, or capital.

hope this : )
