Blaise Pascal Born 1623, Died 1662 Was a French mathematician and philosopher Discovered the “Pascal Law” Invented the Pascaline Also Invented the Syringe and Hydraulic Press Age of 18 became partially paralyzed After that he started to become religious and started pulling away from his work When nearly loosing his life he then devoted himself entirely to his religion
3
Pascal Creation Blaise Pascal DID create the name He did a number of precocious mathematical treatises before the age of 18 to discover what is now known as Pascal's theorem
4
Pressure A force applied to a unit area of surface Units – Pascals (SI unit) Conversions for Pascals 1 atm = 760 mmHg = 101.325 kPa You Tube http://www.youtube.com/watch?v=ctJyu5ete6Y
5
Barometer Invented By – Evangelista Torricelli When – 1644 Measures - pressure of the atmosphere Aneroid Barometer Mercury Barometer
6
Lord Kelvin William Thompson Born- 1824, Died- 1907 British inventor and scientist main theoretical work was in thermodynamics introduced the concept of absolute zero and the Kelvin temperature also worked with James Joule on the Joule- Thomson (or Joule-Kelvin) effect 1896 he was created Baron Kelvin of Largs
7
Kelvin’s Creation worked on heat and electricity in thermodynamics his work of coordinating the theories of heat held by various leading scientists of his time established firmly the law of the conservation of energy as proposed by Joule introduced the Kelvin temperature scale,aka the absolute scale
8
Conversions 1 Pascal = 9.86923267 × 10 -6 atm 1 Pascal = 1.0 × 10 -6 megapascals 1 atm = 101.325 kPa 760 mmHg = 101.325 kPa 1 Atm = 760mmHg 237K=0 o C 1 Kelvin = -272.15 degrees Celsius
9
Practical Applications fraction of 1 atm average altitude (m) (ft) 100 1/25,48618,000 1/e7,91525,970 1/38,37627,480 1/1016,13252,926 1/10030,901101,381 1/100048,467159,013 1/1000069,464227,899 1/10000086,282283,076 -The higher the altitude the less atmosphere there is for us - The lower the altitude the more atmosphere we have - Mount Everest little atmosphere - Marianas Trench a lot of atmosphere
10
Kinetic Theory All matter is composed of very small particles called atoms, ions or molecules. All of these small particles are in constant motion, even at the coldest temperature whether vibratory or translator. The kinetic energy of the particles is a measure of temperature. The greater the number of impacts the greater will be the pressure and vice-versa. These particles collide but the total energy remains same.
11
Kinetic energy and Temp. Kinetic energy- is the energy an object possesses due to its motion The higher the temperature, the faster the molecules move. http://eo.ucar.edu/webweather/molecu les.html http://eo.ucar.edu/webweather/molecu les.html
