Galileo
He created a suction pump that works like and syringe. He was confused why there was a restrincted amount that the heigth of water could rise. -
Evangelist Torricelli
He created the first barometer. He went on with Galieos experiment figuring out that water could come out of underground using the pump due to the atmospheric pressure. He made a closed tube filled with mercury in a pan. The height of the mercury in the tube was equal to the atmospheric pressure. -
Otto von Guericke
He made a pump that used vacum that was very strong. It was so strong it could holed the two hemispheres from coming apart with sixty hores pulling it. Guericke found out that that hemispheres were held together by atmospheric pressure and force not vacum. -
Blasie Pascal
Pascal used the barometer that Torricelli made. Pascal climbed a mountain in south france and found out that the lower you go on the mountain, the higher the atomispheric pressure increases. He also went on with the mercury project of Torricelli. He wondered what type of force kept the murcury in the tube and what filled the space above the murcury that was in the tube. -
Christiann Huygens
He made a manometer. It determined the intermoliculer forces of gase and uses liquid to measure pressure. -
John Dalton
He created a statement that said the total amount of total pressure equal the sum of the two gases combined in a closed containers. -
Joseph Louis Gay-Lussac
He descovered that water was made up of two parts of hygrogen and one part of oxygan which made up water. -
Amadeo Avogadro
The more air you add to an item the bigger it will get because you have increased amount of pressure.The amount of pressure in an item is equal to the amount of particles inside the item.
