Some Web sites of interest and relevance to Physics 260

**Spring 2015**

*Gas pressure:*

Magdeburg hemispheres: Description YouTube

*Simulations:*

**Java
Simulations for Statistical and Thermal Physics**
from
Gould and Tobochnik's excellent curriculum development

**General
references:**

Dealing with Java security settings (on physlet, but generalizable)

**Wikipedia****:
thermodynamics, statistical
thermodynamics, statistical
mechanics, ... **

Compendium of sites for Stat Mech & Thermo, also Nano, Quantum

**Hyperphysics
subsite on Heat & Thermodynamic****s, Light & Vision, and Electricity & Magnetism** : lots of nice calculational modules, also for other subfields

**Heat Basics: **

Cute applet about heat capacity

Diagrams of temperature vs. heat input (and discussions you can ignore): graph 1, graph 2, graph 3, graph 4

Clear, succinct, elementary discussion of thermal expansion

Coefficients of linear expansion of the elements

**Phase Diagrams:**

Thorough gentle discussion of phase diagrams

Concise discussion of phase diagrams

Phase diagram of ice: semilog plot with details of ice phases

*Timely Application of Ideal Gas Law:*

DeflateGate and Gauge Pressure

**Entropy:**

Applet of bouncing ball and entropy

Extensive, non-technical discussion of entropy

Doug Craigen's thought-provoking comments: Entropy and Evolution and Later Summary Notes

*Heat Engines:*

**Brayton cycle **from Wolfram alpha

Brayton cycle turbines for improved thermal-to-electric conversion

**Carnot cycle using Mathematica**, lots of nice adjustments

Carnot cycle, uses Java; try different values of γ = Cp/Cv ; less convenient than preceding

Refrigeration cycle, qualitative

Thermodynamics of refrigeration, with T-S diagrams

Slide show on refrigeration , more than you likely want to know, but the first few are germane

**Otto
cycle-car engine, animated**

**Otto and Diesel with animated p-V diagram** excellent illustration!

Otto cycle on YouTube: comparison of theoretical/idea and practical/actual

Similarly, Diesel cycle on YouTube

Graphical and formal analyses of Otto and Diesel engines, more detailed than you want but nice graph and important conclusion

Graphical analyses of Otto and Diesel engines,again more detailed than you want, with more graphs and less math

**Radiation:**

**Black
body spectrum, inc. total emitted power**

**Interference:**

Thin film interference (alternate site)

Interference for films and other shapes
