Evangelista Torricelli is known for his invention of the barometer in 1643. His original device consisted of a long tube of glass (which contained a vacuum) on top of a larger container of Mercury. The pressure from air pressing down onto the exposed surface of the mercury would push the mercury upwards into the tube; thus, the higher the air pressure, the higher the mercury level. Air pressure was then measured using "millimeters of mercury", which corresponded to the mercury level within the tube.

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.
What is Evangelista Torricelli invention used for today?
Evangelista Torricelli invented the mercury barometer, which is used today to measure atmospheric pressure. Barometers are commonly used in weather forecasting and in monitoring pressure changes in various industrial processes.
When was the first barometer made and by whom?
The first barometer was made by the Italian physicist Torricelli in about 1640.
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 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
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.
What is the unit used to measure atmospheric pressure?

Who invented air pressure?
The concept of air pressure was first discovered by Evangelista Torricelli, an Italian physicist and mathematician, in 1643. He invented the mercury barometer to measure atmospheric pressure, which led to the understanding of how air pressure behaves in different conditions.
What is an example of torricelli's principle?
An example of Torricelli's principle is when you use a barometer to measure atmospheric pressure. The height of the mercury column in the tube of a barometer is determined by the atmospheric pressure pushing down on the mercury in the dish. This is in accordance with Torricelli's principle, which states that the height of a liquid in a tube is inversely proportional to the pressure acting on it.
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.
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.
