Some Web sites of interest and relevance to Physics 260

Spring 2015

Gas pressure:

Air pressure vs. altitude

Magdeburg hemispheres: Description YouTube


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 & Thermodynamics, 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

Thermodynamic equilibrium

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


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 flow

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

Diesel 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

Two-stroke engine, animated .


Black body spectrum, inc. total emitted power

Black body radiation spectrum

Stellar spectra


Superposition of waves

Doppler effect


Thin film interference (alternate site)

Interference for films and other shapes
