Edme Mariotte
French scientist that came up with the Boyle's Mariotte Law, in which pressure and volume are related in an inversely proportional relationship and the number of particles(n) and temperature(T) are constant. The equation for this law is: P1V1=P2V2 -
Jacques Charles
He was a French inventor, scientist, matematician and balloonist who came up with Charles's Law in which volume and temperature have a directly proportional relationship and pressure(P) and the number of particles are constant. The equation for this law is: V1/T1=V2/T2 -
Amedeo Avogadro
Italian chemist that came stated: "At the same temperature and pressure, an equal number of moles of any gas will occupy the same volume."
He also discovered there was a directly proportional relationship between volume(V) and the number of particles( n) at constant T and P. This is called Avogadro's Law and the equation for it is: V1/n1= V2/n2
Avogadro's number= 6.022*×10^23 -
John Dalton
English chemist who proposed that all matter is made of atoms and that these atoms cannot be broken into smaller particles. -
Joseph Louis Gay -Lussac
French chemist and physicist who came up with the Gay Lussac's Law where pressure and temperature have a directly proportional relatiosnhip and the number of particles (n) and volume(V) are constant. The equation for this law is: P1/T1=P2/T2 -
François-Marie Raoult
French chemist that came up with the Raoult's Law. "The vapour pressure of a liquid is the pressure of a vapour in equilibrium with the liquid phase."
The equation for this law is: Vapor pressure of solution (P) = Vapor pressure of pure solvent (Po) *Molar fraction of solvent (Xo) -
James Clerk Maxwell
Scotish scienitst in the field of mathematical physics. He helped the development of Maxwell-Boltzmann Distribution graph which shows:
- Most molecules have medium/low kinetic energy.
- A small percentage will always have a high kinetic energy. -
Ludwing Boltzmann
Austrian physicist whose most important scientific contributions were in kinetic theory, including the Maxwell–Boltzmann distribution for molecular speeds in a gas. The Maxwell-Boltzman Distribution graph shows that:
- Most molecules have medium/low kinetic energy.
- A small percentage will always have a high kinetic energy. -
J.J Thomson
English scientist who came up with the Plum Pudding Model:Was the first scientist to propose that the atom wasn't the smallest particle and that it contained very small negative particles called electrons. He stated this electrons sat in a positively charged jelly that looked like plums in a plum pudding. -
Ernest Rutherford
Australian scientist who came up with a more developed atomic theory by carrying out this experiment: He fired alpha particles at a thin sheet of gold foil and discovered that most particles passed through it but that a small percentage of them were deflected or reflected. -
Niels Bohr
Scientist born in Denmark that used evidence from absorption and emission spectra to create a more developed atomic model.
He came up with 3 very important postulates:
1. Electrons orbit around the nucleus without losing energy.
2. Only some orbits are permitted.
3. Electrons change of orbit by absorbing or emitting the difference of energy between the initial and final level. -
Louis de Broglie
French scientist that came up with the '' wave-particle duality'' that stated that electrons can behave like particles and waves. -
Werner Heisenberg
German physic that came up with the Uncertainity Principle that said that we cannot know the position and mommentum of an electron at the same time.
