Who is the inventor of the barometer?
Evangelista Torricelli
Barometer/Inventors
Although he made important contributions to the field of mathematics, Evangelista Torricelli is best known for his invention of the barometer. Born in Faenza, Italy, on Oct. 15, 1608, he began his education there and later (around 1630) studied in Rome.
Who invented the barometer and which year?
The mercury barometer is the oldest type of barometer, invented by the Italian physicist Evangelista Torricelli in 1643. Torricelli conducted his first barometric experiments using a tube of water.
Why did Torricelli observe small changes in the barometer each day?
Evangelista Torricelli, (born Oct. Torricelli became the first man to create a sustained vacuum. After much observation, he concluded that the variation of the height of the mercury from day to day was caused by changes in atmospheric pressure.
Why did Torricelli use mercury in his barometer?
Torricelli concluded that the mercury fluid in the tube is aided by the atmospheric pressure that is present on the surface of mercury fluid on the dish. He also stated that the changes of liquid level from day to day are caused by the variation of atmospheric pressure.

How did Torricelli invented barometer?
The first mercury filled glass tube was generally accepted to have been invented in 1643 by Torricelli, which became known as Torricelli’s mercury barometer. In this he produced a vacuum by filling a glass tube with mercury, inverting it and then submerging the open end in a vessel of mercury.
Did Mendeleev invented barometer?
Mendeleev was a versatile genius. He worked on many problems connected with Russia’s natural resources. He invented an accurate barometer. Mendeleev name was immortalized by naming the element with atomic number 101, as Mendelevium.
How did Evangelista Torricelli barometer work?
Who invented the mercury barometer Newton Watt Torricelli Galileo?
Evangelista Torricelli (tawr-ih-CHEL-ee) invented the barometer in the 1640s. He filled a glass tube with a liquid metal called mercury, and then placed the tube upside down in a dish.
Did Galileo invent the barometer?
The development of the barometer began at the end of the 16th century. Galileo Galilei used water and air in an inverted glass vessel to study temperature. This experiment created the first barometer.
Why did Evangelista Torricelli invent barometer?
Evangelista Torricelli became the first scientist to create a sustained vacuum and to discover the principle of a barometer. Torricelli realized that the variation of the height of the mercury from day to day was caused by changes in the atmospheric pressure. Torricelli built the first mercury barometer around 1644.
How does a Torricelli barometer work?
(The first barometer of this type was devised by Italian physicist and mathematician Evangelista Torricelli in 1643.) The barometer works by balancing the weight of mercury in the glass tube against the atmospheric pressure, much like a set of scales.
What does Torricellian barometer mean?
A mercury barometer (also known as a Torricellian barometer) consists of an open flat container filled with mercury. A glass tube with one end sealed is placed in the center of the container. The open end is positioned at the bottom inside the mercury.
How did Evangelista Torricelli invent the barometer?
Evangelista Torricelli became the first scientist to create a sustained vacuum and to discover the principle of a barometer. Torricelli realized that the variation of the height of the mercury from day to day was caused by changes in the atmospheric pressure.
What barometer is the most commonly used barometer?
Initially, water-based barometers were used, later it was replaced by mercury and aneroid barometers which the two most commonly used barometers. The mercury barometers have a simple construction.
How do you calculate barometer?
To calculate barometric pressure, look at a barometer and write down the pressure reading. Then, check back in an hour and write down the new reading. Once you have both readings, subtract the current pressure from the pressure an hour ago to determine how much the barometric pressure has risen or fallen.
