Class 11 Physics simulations · Kinetic Theory

Maxwell–Boltzmann speed distribution

Compare a gas at two temperatures and distinguish most probable, mean, and RMS speeds.

Open the simulation

What to notice

Heating broadens the distribution and moves its peak to a higher speed; the total probability stays one.

Key relation

vmp < vmean < vrms

Try this

Keep the gas mass fixed and double the comparison temperature.

What you can change

• Primary temperature: 200 to 800 K
• Comparison temperature: 200 to 1000 K
• Molar mass: 2 to 44 g/mol
