The Watt steam engine (alternatively known as the Boulton and Watt steam engine) was the first type of steam engine to make use of steam the new design replaced Newcomen engines in areas where coal was expensive, and then went on to be used in the place of most natural power sources such as wind and water. A Scottish instrument maker, James Watt, was given the job in 1763 of repairing a model Newcomen engine for the University of Glasgow, and noted how inefficient it was. In 1765 Watt conceived the idea of a separate condensation chamber. Watt's idea was to equip the engine with a second, small cylinder, connected to the main one. In Watt's design, the cold water was injected only into the condensation chamber. Watt's engine soon became the dominant design for all modern steam. A unit of power called the Watt was named after James Watt.
In contrast with the middle and upper classes, the "working" class was not well off. In the working class, many were replaced in factories by machines. But on the other hand, many also gained new jobs in factories working with machinery. The average adult worker worked quite often: five to seven days of the week, for more than half the day per shift. Children as young as fifteen worked for minimal wages. Some of the children became deformed or crippled due to their work, which was often. Most workers worked for relatively low wages due to their incapability to produce goods.
The women and children were not paid as much as the men were. The housing was not desirable either – for example there was frequent overcrowding. The housing had unsanitary features, which led to diseases. Workers who were desperate lived near a factory. What also made life difficult during the Industrial Revolution was that there were limited privileges such as few people voted, nor were they allowed to do anything to improve their working condition that was legal.
