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 hurricanes and tornadoes

• Because it would lead to extreme weather events

• Because it would correlate to temperature

What is the main purpose of a barometer?

• To measure air pressure

• To predict hurricanes and tornadoes

• To create a vacuum

• To measure temperature

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

• Galileo Galilei

• Gasparo Berti

• Evangelista Torricelli

• Blaise Pascal

What did Gasparo Berti do to create a stable vacuum?

• Filled a tube with water and opened the bottom end

• Filled a tube with mercury and opened the bottom end

• Filled a tube with water and opened the top end

• Filled a tube with mercury and opened the top end

What did Evangelista Torricelli propose was influencing the water in the tube?

• The weight of the air surrounding the pool

• The force of the vacuum inside the tube

• The temperature of the water in the tube

• The pressure from the water column inside the tube

What did Torricelli use instead of water in his experiment?

• Mercury

• Air

• Oil

• Steam

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

• Mercury was denser and fell farther than water

• Mercury was easier to obtain than water

• Mercury was less toxic than water

• Mercury was more readily available than water

What did Blaise Pascal demonstrate with the mercury tube experiment?

• The mercury level dropped as the atmospheric pressure decreased with altitude

• The mercury level increased as the atmospheric pressure decreased with altitude

• The mercury level remained the same regardless of altitude

• The mercury level increased as the atmospheric pressure increased with altitude

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

• Restrictions on the use of mercury due to its toxicity

• The invention of a more accurate measuring instrument

• The decline in demand for barometers

• The discovery of a new method to measure atmospheric pressure

What does the invention of the barometer demonstrate?

• The importance of thinking outside of the box

• The limitations of ancient philosophers' theories

• The significance of air pressure in weather forecasting

• The impact of mercury on scientific experiments
