James Watt - Suggestions from the lid of the kettle

James Watt (1736 - 1819): As an English inventor, he was trained in his family from an early age and mastered basic manufacturing techniques. At the age of 18 Watt went to study measuring instruments manufacturing techniques at Glasgow school, which laid a good foundation for Watt to improve the steam engine Niucômanh.

After years of efforts, he finally built the world-famous Oat steam machine, greatly promoting industrial production performance. In 1785 became a member of the British Academy of Sciences. Watt's dedication deserves to be named: "He laid the foundation for the industrial revolution ".

Watt was born on January 19, 1736 in the town of Greenork near Glasgow, England.

Picture 1 of James Watt - Suggestions from the lid of the kettle At the age of 8, once at the grandmother's house, she boiled water, when the water boiled on the stove, the steam came out from its trunk, then the lid was warm, "Bach, Bach, Bach" danced continuously on the warm mouth, at the same time. There is a lot of steam flying up. Watt felt very excited, he watched intently, not understanding what evil spirits were doing.

For a long time, intense curiosity gave him the courage to open the lid with his hand.

The steam coming from the warmth rises to the sky. Watt opened his curious eyes, and there was nothing else in the water.

It's strange, Watt thought.

Watt ran out and pulled his grandmother's hand into the house and asked her: "What pushes the lid of the kettle, makes it keep jumping up and down forever?"

The grandmother slowly said, "I have something to do with it, it is boiling water."

"Why is the water boiling and the lid warming up?" - Watt did not understand asking her grandmother.

"Because of the steam, don't you see the steam coming up from that warm faucet?"

So where does the steam come from? Why does it run to the faucet? "

"Grandmother's sweetie, it comes from the hot water, after the water boils, it produces steam."

"Is that so!"

Watt mused for a moment and then asked her:

"The thrust of the steam is so big, isn't it? There is a lot of water where the water vapor is open and the lid is warm, if you use a lot of water, the thrust must be great, isn't it? If the steam is very strong, you can lift it. Very heavy things right? "

"Yes, yes, you don't know, wait, I'll know!" Seeing that she couldn't answer, Watt thought deeply.
