Ideal Gas Law (PV = nRT)Live
Pressure

kPa (1.03 atm)

Controls

Set moles, temperature, and volume — pressure follows from PV = nRT. Compress the volume or heat the gas and watch the pressure climb.

Governing equation

Reading this result: At 300 K, 1 mol in 24 L, PV = nRT gives about 103.9 kPa (1.03 atm). Mean molecular speed scales with the square root of temperature, so this gas moves about 1.00x as fast as it would at 300 K. Around room temperature the molecules carry moderate kinetic energy. Expanding the volume spreads the molecules out, lowering the collision rate and the pressure.

Maxwell Boltzmann

Maxwell–Boltzmann DistributionLive

Controls

Gas molecules do not all move at one speed — they spread into this distribution. Heat the gas or lighten the molecule and the curve broadens and shifts faster.

Presets

Data Inspector

Most probable0 m/s
Average0 m/s
RMS0 m/s

Governing equation

Reading this result: The peak (v_mp 0 m/s) sits below the average and RMS speeds because the long high-speed tail pulls those means upward.

Gas in a Box — Kinetic TheoryLive

Controls

Pressure emerges from molecules hammering the walls. More particles or higher temperature → higher pressure, exactly as PV = nRT predicts.

Particles120
Temperature3.0
Pressure (wall)0
LawPV = nRT

Governing equation

Reading this result: Pressure scales with both particle count and temperature: doubling either roughly doubles the force on the walls (P ∝ nT).

Frequently asked questions

What is the Gas Process Kit multi-solver?
Gas Process Kit is a guided workflow that chains 3 individual PolySim solvers into one end-to-end analysis, piping each result into the next step.
Is it free to use?
Yes. Every step runs entirely in your browser using real numerics — no install, no account, no cloud cost. Custom or private solver packs are available as a paid service.
