For instance, the internal energy is given by: by: $$U = \sum_i P_i E_i$$ Note that this will probably not be an eigenvalue of the energy, but that's okay. The energy eigenvalues are so close for the total energy of a macroscopic object that we couldn't distinguish them anyhow… text/html 2018-09-03T06:18:58-08:00 http://sites.science.oregonstate.edu/portfolioswiki/courses:order20:eeorder20:eediatomic?rev=1535980738 In-class Content Lecture: Reviewing Several Energy Eigenvalues (10 minutes) Lecture notes from Dr. Roundy's 2014 course website: I'm going to quickly review and introduce the energy eigenvalues for some simple quantum mechanical problems.

So we could maximize the fairness by $$\frac{\partial\mathcal{F}}{\partial P_i} = 0$$ $$= -k_B (\ln P_i + 1)$$ Using the formula for the fairness function, what can this tell us about $P_i$?

Starting next week, we will be studying statistical mechanics. Thermodynamics may look ``theoretical'' because it involves a lot of math, but ultimately it is an experimental science.

But it is useful to look at those two non-state variables work and heat. Both are changes in energy of a system, so we can write the first law as $$\Delta U=Q+W$$ where $U$… text/html 2018-09-03T06:20:38-08:00 http://sites.science.oregonstate.edu/portfolioswiki/courses:order20:eeorder20:eefreeexpansion?rev=1535980838 In-class Content Activity: Free Expansion Not-Quiz and Discussion Link to Free Expansion Not-Quiz and Discussion Activity Activity Highlights Homework text/html 2018-09-03T05:46:08-08:00 http://sites.science.oregonstate.edu/portfolioswiki/courses:order20:eeorder20:eeheatandtemp?rev=1535978768 Link to Prereqs In-class Content Lab: Ice Calorimetry Lab Link to Ice Calorimetry Lab Lab Highlights SWBQ: Comparing Thermodynamic Properties Link to Comparing Thermodynamic Properties Small White Board Question Lecture: Dulong and Petit Rule (5 minutes) Ice Calorimetry Lab Lecture notes from Dr. Roundy's 2014 course website: In 1819, shortly after Dalton had introduced the concept of atomic weight in 1808, Dulong and Petit observed that if they measured the specific heat per unit mass… text/html 2018-09-03T05:58:17-08:00 http://sites.science.oregonstate.edu/portfolioswiki/courses:order20:eeorder20:eeicelabtwo?rev=1535979497 In-class Content Lecture: Ice Calorimetry Lab II Linke to Ice Calorimetry Lab II Lab Highlights text/html 2018-08-31T12:13:50-08:00 http://sites.science.oregonstate.edu/portfolioswiki/courses:order20:eeorder20:eelegendre?rev=1535742830 In-class Content Lecture: Thermodynamic Energies Naming Thermodynamic Variables Lecture notes from Dr. Roundy's 2014 course website: We begin with the now-familiar thermodynamic identity $$dU=TdS-pdV$$ Remember in the Interlude I talked about what if one of the weights were hidden in the black box, so you could not change it, or measure its position?
