Gas Laws Sandbox
Change one variable. Watch the gas respond. Choose a law to lock two variables, then adjust either of the two unlocked controls.
Particle model
Gas controls
Control limits adjust together so the other variable stays in range. Locked values stay fixed until you choose another law or reset.
Live graph
The curve shows the model at the current locked values. The blue point is your current setting.
PV = nRT
R = 0.0821 L·atm/(mol·K)
Readouts show 3 significant figures. Calculations use full precision. Reset uses 1 atm, 273 K and 1 mol, giving 22.4133 L (displayed as 22.4 L).
Ideal gas model: particles have negligible volume and no attractions. Real gases can depart from this model, especially at low temperature or high pressure.
