Period: to
Discoveries and expirements of 17th and 18th centuries.
Time of great scientific discovery and advancments in science. -
Toricelli invents the Barometer.
Torricelli invents the baramoter which is used to measure atmoshperic pressure. This is used in Chemistry to compre the pressure of the air to other gases. -
Boyle defines his Law of pressure and volume.
Robert Boyle publishes the second addition of "Physico-Mechanicall, Touching the Spring of the Air and Its Effect." where he describes the relationship between volume and pressure later known as 'Boyle's Law'. -
Joseph Priestly discovers Oxygen
Joseph Priestly burned a compound of mercury oxide and discovered that it turned into a gas. By placing a candle in the gas priestly noticed that it caused the flame to burn brighter. After placing a mouse in the gas for a period that lasted four times as long as any other gas, he realized the gas supported life. -
Jacques Charles reinvents the hot air baloon and partially discovers "Charles Law".
Jacques Charles invents the Hot air baloon. He is also later credited with the finding of "Chalres Law". Gay-Lussac confirmed many of his studies and found out the inverse relationship between pressure and temperature, and from there decided to publish his findings giving credit to Charles. -
John Dalton defines his atomic theory.
Dalton releases the first details about his atomic theory detailing atoms. His theory had four main points: All matter is composed of indivisible particles called atoms, all atoms of a given element are identical;atoms of different elements have different properties, chemical reactions involve the combination of atoms, not the destruction of atoms, and when elements react to form compounds, they react indefined,whole-number ratios. -
Gay-Lussac proclaims his new law
Gay-Lussac declares the " Gay-Lussac Law." In which he determined that "the density of an ideal gas at constant pressure varies inversely with the temperature." in other words pressure and tempurature are inversely related, meaning they create opposite effects of each other when changed. -
Avagadro develops his hypothesis and law.
Avagadro proposes his theory in a publication in 1811 and later develops his law. This law states " under conditions of constant pressure and temperature, there is a direct relationship between the volume and number of moles for an ideal gas." Meaning when pressure,temperature, and volume are the same in a gas, the number of particles in the gas are also the same. Avagadro is also known for helping develop the mole, which is a form of a unit of measurment in chemistry.
