Document Summary
The first time you go through it, you don"t understand it at all. The second time you go through it, you think you understand it, except for one or two small points. The third time you go through it, you know you don"t understand it, but by that time you are so used to it, it doesn"t bother you anymore. - arnold sommerfeld. Work and heat: heat and work are not possessed by systems. Examples: a piston cylinder contains air at 1000 kpa, 800 k with a volume of 0. 05 m^3. The piston is pressed against the upper stops and it will float at a pressure of 750 kpa. Then the air is cooled to 400 k. what is the process work: a 10-m high cylinder, cross-sectional area 0. 1 m^2, has a massless piston at the bottom with water at 20 c on top of it.
