Otto Van Guericke
Background of Otto Van Guericke
-Otto Van Guericke was a German Physicist, engineer, and natural Philosopher.
-invetnted the first air pump and used it to study vacuum and the role of air in combustion and respiration
-in 1654, an experiment of his was performed for Emperor Ferdinand III which involved him putting two spheres together and removing the air from in between them, creating a vacuum and could not be pulled apart -
Evangelista Torricelli
Backgroung of Evangelista Torricelli
-Italian physicist and mathematician
-invented the barometer, scientific instrument used to measure atmospheric pressure
-filled a glass tube, 4 feet long with mercury and inverted the tube into a dish, observing that some of the mercury did not flow out and that the space above the mercury in the tube was a vacuum.
-died October 25, 1647 -
Blaise Pascal
Background of Blaise Pascal
-french mathematician, physicist, and religious philosopher
-became known for Pascal's law of pressure (states that pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such that the pressure variations remain the same)
-further validated Evangelista Torricelli's theory of barometrical variations
-died August 19, 1662 -
Robert Boyle
Background of Robert Boyle
-Irish natural philosopher and theological writer
-published his law in 1662 (P1V1=P2V2)
-his law helps us understand the direct relationship between the pressure of a gas and it's volume
-died December 31, 1691 -
John Dalton
Background of John Dalton
-English meteorologist and chemist
-pioneer in the development of the modern atomic theory
-credited with Dalton's law of partial pressures which states that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases.
-died July 27, 1844 -
Amadeo Avogadro
Background of Amadeo Avogadro
-Italian mathematical physicist
-known for his law, Avogadro's law which states that under controlled conditions of temperature and pressure, equal volumes of gases contain an equal number of molecules, first stated in 1811
-died July 9, 1856 -
Joseph-Louis Gay-Lussac
Background of Joseph-Louis Gay-Lussac
-French chemist and physicist
-investigated behaviour of gases, established new techniques for analysis
-well known for his law stating that P1/T1 = P2/T2 stating that if the volume of a container is held constant as the temperature of a gas increases, the pressure inside the container will also increase
-died May 9, 1850
