Barometer and the Invention of Vacuum

According to Aristotle, why couldn't a true vacuum exist?

• Because the surrounding matter would immediately fill it

• Because it would cause extreme weather events

• Because it would lead to the invention of the barometer

• Because it would contradict the theory of ancient philosophers

What is the main purpose of a barometer?

• To measure air pressure

• To predict hurricanes and tornadoes

• To create a vacuum

• To study the theory of Aristotle

Who conducted the experiment to demonstrate the possibility of a vacuum?

• Gasparo Berti

• Galileo Galilei

• Evangelista Torricelli

• Blaise Pascal

What did Gasparo Berti do to create a stable vacuum?

• Filled a long tube with water and opened the bottom end

• Filled a long tube with mercury and opened the bottom end

• Filled a shallow pool with water and opened both ends of the tube

• Filled a shallow pool with mercury and opened both ends of the tube

What did Evangelista Torricelli propose as the influencing factor on the water level in the tube?

• The pressure from the air surrounding the pool

• The force of the vacuum inside the tube

• The weight of the water column inside the tube

• The weight of the mercury column inside the tube

What did Torricelli use instead of water in his experiment?

• Mercury

• Air

• Gas

• Steam

Why did Torricelli use mercury instead of water in his experiment?

• Because mercury was denser and fell farther

• Because mercury was lighter and rose higher

• Because mercury was easier to measure

• Because mercury was less toxic than water

What did Blaise Pascal demonstrate with the mercury tube taken up a mountain?

• The mercury level dropped as the atmospheric pressure decreased

• The mercury level rose as the atmospheric pressure decreased

• The mercury level remained the same regardless of altitude

• The mercury level increased as the atmospheric pressure increased

What was the main reason for mercury barometers to no longer be produced in Europe?

• Restrictions on the use of mercury due to its toxicity

• Advancements in technology making them obsolete

• Lack of demand for barometers

• Discovery of a more accurate measuring instrument

What does the invention of the barometer by Torricelli demonstrate?

• The importance of questioning long accepted beliefs

• The limitations of ancient philosophers' theories

• The significance of air pressure in weather forecasting

• The necessity of using mercury in scientific experiments
