BENG 130 Lecture 1: Lecture 01
Document Summary
Lecture 01: as engineers, we want to define the state of a system, and we also want to define the variables in the state of the system. Theoretically, if we looked at it microscopically, we could define xyz position and xyz velocity for every argon atom, but we"d need 6 moles of variables to do so. This is unnecessary, and instead, we can define the system by pressure, temperature, volume, etc. Open vs. closed systems: open system: you can exchange mass, closed system: you can"t exchange mass. A glass of water (no water leaves the glass or gets added to it) A) what is the maximum work you can extract? (in other words, what is the minimum work you can do to affect the change?) How do the variables of the system predict the phase of matter: 9) how many components do i have in my system, note that we never asked how fast does the state change? .
