A teaching tape for LQ-05, Independent Configurations and Boltzmann Entropy

The locked positions

Demonstrates that the probability is (V/V0)^n only when the points are independent; rigidly locked points give V/V0.

Where it starts

The settings the tape begins from, under the constant set modern-si-2019. Values are the model's own, not the laboratory control's display: a radius of 5e-7 is half a micrometre.
SettingValue
Number of Particles (n)10
Subvolume Fraction (f)0.5
Sampling Trials (trials)10000

What it changes, and what to expect

  1. Step 1

    Ten independent particles in half a volume

    With 10 independent points, W = (1/2)^10 = 1/1024.

    What the author recorded that a reader should see here.

  2. Set Number of Particles (n) to 60 changes what the run starts from

    Ten locked particles moving rigidly

    When the 10 points are rigidly locked, W = 1/2.

These are the values the tape's author recorded, not a result this page computed. Nothing here runs the instrument. Open LQ-05 with these settings: the link opens it with them already in place. Compare what it gives you with what is recorded here. The settings travel in the link and the laboratory reads them as it loads, so without JavaScript it opens at its worked example instead.
