industries
Explanation:
- The first steam engine was built in 1698, and by the time Watt was born, the machines, perfected by Thomas Newcomen, were already pumping water from mines throughout the country.
- Sometime around 1764, Watt was given a model of the Newcomen machine to repair it.
- Realizing that it was impossible to repair her, he began to work to improve it.
- He added a separate condensation chamber that prevented excessive steam loss. He patented a new, improved model of a steam engine in 1769.
