History Inventions That Revolutionized The world

This week I learned about three inventions and an inventor. They are the vapor-compression-theory, Oliver Evans, percussion ignition, and the canning process. They all were invented in the 1700s to1800s.

Vapor-compression-theory is how you keep your refrigerator cold, and preserve your food. It also keeps your fridge closed by pressurizing air and making kind of like a barrier in between cold and warm air. It cycles warm air out and cold air in. It also keeps food cold to slow decay and mold. At first it was used to keep ice cold, so people can have ice water and a cold house. Then it made life easier. It was invented in the late 1700s.

Oliver Evans was the one who invented the vapor-compression-theory, and the one who invented the better flour milling process. He revolutionized the flour industry, and helped with the fineness of the cloth. It was a great discovery, and it helped other people by making it easier to make fine cloth, or more expensive cloth. It was invented in the early 1800s.

The percussion ignition is a tool made that made a firearm deadlier than anything else. It was used to fight in The French Revolution because it was the most effective weapon they had. Percussion ignition is a process that creates an explosion making the gun fire a bullet. It was invented in the 1807.

The canning process is the process of putting food into a jar to preserve it. It can preserve food up to 110 years, but only if it is cold. It was very helpful to the food industry because they could preserve food for very long periods. It usually holds fruits and veggies. 

These all were very helpful to society in the way they were used to protect, preserve, and to invent. They were very helpful back then because people did not know how to solve the problems they had, and these inventions and inventor, solved them.
