What did Evangelista Torricelli invent?
Evangelista Torricelli is famous for inventing the barometer, a scientific instrument used to measure atmospheric pressure. His invention revolutionized the field of meteorology and laid the foundation for understanding weather patterns.
Who invented the barometer?
Barometer is an instrument used to measure atmospheric pressure.The first barometer was built by Francis Bacon. Later in 1644, Evangelista Torricelli, built the first instrument with mercury.
What did Torricelli state when he invented the barometer?
Torricelli stated that the height of a column of liquid in a tube was determined by the pressure exerted on the liquid at the base of the column. This discovery led to the invention of the barometer, a tool used to measure atmospheric pressure.
Who invented the compass on a keychain?
The compass on a key-chain idea was invented many years ago. This invention is still used today by many people. Honestly, there is no "for sure" inventor of this, people just started doing it and this idea became more known.
What was Galiloe's invention?
Galileo didn't invent anything he just helped improve the telescope.

Who discovered mercury barometer?
The mercury barometer was invented by Italian scientist Evangelista Torricelli in 1643. Torricelli's innovation allowed for accurate measurement of atmospheric pressure using mercury as the working fluid in a glass tube.
Who is the inventor of barometer?
Evangelista Torricelli , 1608-47, Italian physicist and mathematician. He was Galileo's secretary (1641-42) and his successor as professor of philosophy and mathematics at Florence. He invented the barometer (1643), called the Torricelli tube

What is a Torricelli tube?
A Torricelli tube, named after Italian physicist Evangelista Torricelli, is a simple device used to measure fluid levels, typically in applications where accurate barometric pressure measurements are needed. It consists of a vertical glass tube open at the top and submerged in a fluid-filled reservoir. The height of the fluid column in the tube is proportional to the pressure of the fluid above it.
What did Evangelista Torricelli state after inventing the first mercury barometer in 1643 that is used in meteorology to determine air pressure and help predict the weather?
we live at the bottom of an ocean of air, which we know has weight.
Who discovered atmospheric pressure?
Evangelista Torricelli discovered atmospheric pressure. Secretly, he created an expierement with some of his friends. By filling a bowl with mercury and placing a six foot long glass tube upside down into it, a vacuum was created, causing the mercury to rise up. This was an early barometer. The reason this expierement was kept secret was probably because in 1643, this would have been considered witchcraft because a vacuum was considered impossible.

Who invented a the bareometer?
The first barometer was devised in 1643 by Evangelista Torricelli. Torricelli had set out to create an instrument to measure the weight of air, or air pressure, and to study the nature of vacuums. He used mercury, perhaps on a suggestion from Galileo Galilei, because it is significantly denser than water. To create a vacuum with water takes a column over 30 feet long, while with mercury it takes less than four feet.
Named after inventor Evangelista Torricelli the torr is a unit of measure for what property?
The torr is a unit of measure for pressure. It is defined as the pressure exerted by a column of mercury that is 1 millimeter in height, under standard gravity. It is commonly used in scientific and engineering applications to measure low pressures.
