-

-
created some of the first practical vaccume oumps and created the manometre which studeis the elastic forces in gases
-
Christiann Huygens was born in The Hague, Netherlands
-
Galileo dies in Arcetri Italy
-
he assisted Galileo with some work. he also invented the barometer. he poured murcury into a tube and put it in a dish, and thats when he found out the vaccume was a success. he was the first to create a good working vaccume.

-
he created a vaccume pump that was supposed to pull air from whatever it was connected to
-
Geuricke died in Hamburg Germany
-
proposed that equal volumes of diferent gases had an equal number of molecules when thay are the same temperature and have the same pressure
-
he combined volumes and realized that two volumes of hydrogen and one volume of oxygen mad two volumes of water. also preformed experaments with pressure in hot air balloons.
-
daltons law: the total pressure of a mixture of gases amounted to the sum of the partial pressures that each individual gas exerted while occupying the same space
