Question

James Watt was born in Greenock on 19 January 1736. His father, also called James, was a ship builder. As a boy Watt went to the local grammar school where he studied classics and mathematics. The young Watt also liked making models.

Eventually, Watt decided to become a maker of mathematical instruments, such as quadrants and compasses. In 1755 he went to London, but only stayed there for two years before moving to Glasgow.

In 1764 Watt made a model of Newcomen steam engine. In this engine, the steam was pushed into a cylinder, then condensed back into water. A year later Watt realized it would be more efficient to condense the steam in another chamber separate from the cylinder. However, it was not until 1769 that Watt patented his new idea, the separate condenser.

In 1775 he went into partnership with Matthew Boulton and began making steam engines which were used for pumping water out of mines. By 1780 the Industrial Revolution was beginning to transform life in Britain and Watt adapted his steam engines to provide a rotary motion so they could be used to power machines in new factories.

In 1781 he used the sun to do this and four years later, steam engines were used to power machines in cotton mills for the first time. Meanwhile, in 1782 Watt invented another major improvement, the double–acting steam engines. In 1788 he invented the fly ball Royal to regulate the speed of steam engines and he made a pressure gauge in 1790.

In 1785 Watt was elected a fellow of the Royal society and he retired from business in 1800. James Watt died on 25 August 1819 and was buried in Birmingham.

What was happened to James’s life before 1782?
a. Invented the double-acting steam engines..
