Entropy for a copper wire
Simulate a copper wire live in your browser. This runs the real Entropy solver — adjust the inputs, watch it respond instantly, and export the result. No install, no account.
Controls
Gas confined to one half rushes to fill the whole box the instant the partition is removed — and never spontaneously crowds back. That irreversibility is the second law: entropy, a measure of disorder, always increases. For doubling the volume the entropy rises by nR·ln2, purely because there are vastly more ways to be spread out than packed in.

About this simulation
The full Entropy tool models a copper wire with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.

Frequently asked questions
- How do I simulate a copper wire?
- Open this page and use the live Entropy tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.
- Is it free?
- Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.
- Can I use my own numbers?
- Absolutely — every input is adjustable, and with data import you can drive a copper wire from your own measurements.
