GENERAL KNOWLEDGE

Detailed explanation-1: -James Watt was an 18th-century inventor and instrument maker. Although Watt invented and improved a number of industrial technologies, he is best remembered for his improvements to the steam engine.

Detailed explanation-2: -Newcomen’s engine was gradually replaced after 1775 in areas where coal was expensive (especially in Cornwall) by an improved design, invented by James Watt, in which the steam was condensed in a separate condenser.

Detailed explanation-3: -In Watt’s engine, condensation activity is moved to a separate and perpetually cooled chamber. The steam condenses faster and the cylinder remains perpetually hot. The result: Watt’s machine is twice as fast as its predecessor. It’s a huge success, however, it only exists on paper.
