The question asks to identify the inventor of the spinning mule, a significant invention during the Industrial Revolution that combined features of earlier spinning machines. This requires knowledge of key inventors and their contributions to textile machinery.
C) Samuel Crompton — Samuel Crompton invented the spinning mule in 1779. This machine was a hybrid of James Hargreaves' spinning jenny and Richard Arkwright's water frame. It produced yarn that was both strong and fine, making it suitable for a wider range of textile products and significantly advancing the textile industry.
The question asks to identify the inventor of the power loom, a key invention during the Industrial Revolution that mechanized weaving. This requires knowledge of significant inventors and their contributions to textile machinery.
Correct Option: B) Edmund Cartwright
The question asks about Richard Arkwright's historical significance, specifically his role in establishing large-scale, water-powered cotton mills. This points to a major shift in production methods during the Industrial Revolution.
Correct Option: B) Factory system of centralised, mechanised production
The question asks to identify the inventor of the earliest practical steam engine, specifically one used for pumping water out of coal mines in the early 18th century. This requires knowledge of the history of the Industrial Revolution and key inventors.
Correct Option: A) Thomas Newcomen
Thomas Newcomen developed the atmospheric engine in 1712. This engine was the first practical steam engine and was widely adopted, particularly for pumping water out of deep coal mines, which was a major problem at the time. His engine used steam to create a vacuum, allowing atmospheric pressure to push a piston down, thus performing work.
The question asks to identify the Scottish engineer who significantly improved the efficiency of the early steam engine, making it a practical industrial power source. This requires knowledge of key figures in the history of the Industrial Revolution and steam engine development.
Correct Option: D) James Watt
James Watt, a Scottish engineer, is renowned for his fundamental improvements to the Newcomen steam engine in the 1760s. His most significant innovation was the invention of the separate condenser, which drastically reduced fuel consumption and increased the engine's efficiency. By keeping the main cylinder hot and condensing steam in a separate, cool chamber, Watt's engine could operate much faster and more economically. This made the steam engine a practical and versatile power source, driving the Industrial Revolution.
The question asks about the significance of James Watt's improved steam engine during the Industrial Revolution. We need to identify the key contribution that made it transformative.
C) A reliable, powerful and location-independent source of mechanical energy for factories and machinery. Watt's engine was far more efficient and powerful than its predecessors. The ability to generate mechanical energy anywhere, not just where water power was available, was crucial. This led to the growth of factories and the widespread mechanization of industries, fundamentally changing manufacturing and society.
