Class 11 Physics simulations · Thermodynamics

Gas under a piston

Compress or heat an ideal gas and watch its pressure respond.

Open the simulation

What to notice

At fixed temperature, a smaller volume means a larger pressure.

Key relation

PV = nRT

Try this

Halve the volume while holding temperature and gas amount fixed.

What you can change

• Gas volume: 4 to 30 L
• Temperature: 200 to 600 K
• Amount of gas: 0.5 to 3 mol
