What is thermodynamics? Wikipedia:Thermodynamics is the science of energy conversion involving heat and other forms of energy,most notably mechanical work. Ours:Thermodynamics therme(heat)+dynamis(power) natural extension of the"mechanical world dynamics"to applications involving temperature effects. Science and engineering on most efficient conversion of energy and heat into useful work recognizing we have finite resources (total energy)at our disposal;Impact on environment (soil,water,air-local,state,country, earth)and society. This course basic concepts laws fluid property fundamental process +cycles applications. Thermodynamics:Promising career growth opportunities!!!! 上游充通大 February 28,2018 8 SHANGHAI JLAO TONG UNIVERSITY

The beginning of Thermodynamics Otto von Guericke (Mayor of Magdeburg) in1650, built and designed the world's first vacuum pump and demonstrated a vacuum using his Magdeburg hemispheres. Support Evangelista Torricelli's finding; To make a vacuum in order to disprove Aristotle's long-held supposition that 'nature abhors a vacuum'. Shortly after Guericke,the English physicist and chemist Robert Boyle had learned of Guericke's designs and,in 1656,in coordination with English scientist Robert Hooke,built an air pump.[17]Using this pump,Boyle and Hooke noticed a correlation between pressure,temperature,and volume. 到之人入子 February 28,2018 9 SHANGHAI JLAO TONG UNIVERSITY
