CEM142 1nd Edition Lecture 14 Outline of Last Lecture I. Introduction to the first law of thermodynamicsOutline of Current Lecture II. Finish the first law of thermodynamicsIII. Introduction to the second law of thermodynamicsCurrent Lecture-law “0”: if A is in thermoequilibrium with B and A is also in thermoequilibrium with C, then B is in thermoequilibrium with C-thermoequilibrium is unique, there is only one kind-law 1: deltaE = q + w (the change in energy is equal to heat plus work)-some of this lecture was a review from last lecture. He just went into more detail about these different types of systems to make sure that we really understood them-also, a lot of these equations will be on the equation sheet provided for the exam. You only need to memorize a few of the equations (the ones that I have bolded) but make sure that you in what types of problems you can apply all of the equations1. expansion against constant pressure-w=-PdeltaV-qp=nCpdeltaT=(5/2)RndeltaT-deltaE=w+qp-2. Change of pressure with constant volume-w=0-qv=nCvdeltaT=(3/2)RndeltaT-deltaE=qvThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.-3. Reversible and isothermal expansion/compression-PV=nRT-P=(nRT)/V-w=-nRTln(Vf/Vi)-deltaE=0 because it is isothermal-q=-w-4. Adiabatic expansion/compression-q=0-deltaEAC=deltaEAB+deltaEBC=0+qBC=qBC=(3/2)RndeltaT-law 2: disorder increses-nature always proceeds toward more disorder in a system-solid: most ordered-liquid: intermediate-gas: least ordered-entropy
