Simulate PV=nRT with animated gas particles. Adjust pressure, volume, temperature, and moles to see real-time changes.
Manipulate pressure, volume, absolute temperature, and gas amount while the Ideal Gas Law Simulator applies PV = nRT and animates gas particles as the settings change. It is for linked-state questions, such as how compression affects pressure or how added moles alter a gas at fixed temperature. The usual mistake is a unit mismatch. Temperature in this equation is thermodynamic temperature, so Celsius readings need conversion to kelvins, and the numerical value of R must be compatible with the pressure and volume units used.
An equilibrium state is consistent when pressure times volume equals the amount in moles times the molar gas constant times absolute temperature. Once the units and three quantities are fixed, the fourth is determined. For a controlled comparison, leave n and T unchanged to study P versus V, or leave n and V unchanged to study P versus T.
The animated particle view follows the selected gas state, giving a microscopic-style picture beside the macroscopic variables. In kinetic theory, higher absolute temperature means greater average translational kinetic energy, and compression gives the gas less space at the same amount. Use the motion and spacing to compare settings. The equation and displayed numbers, rather than counting drawn particles or collisions, carry the quantitative result.
Not directly as T in PV = nRT. Convert it to kelvins unless the temperature control explicitly performs that conversion. Add 273.15 to the Celsius value, so 25 C becomes 298.15 K. Temperature ratios must also use kelvins: changing from 25 C to 50 C does not double the thermodynamic temperature.
Yes only when the gas amount and volume remain fixed and temperature is measured in kelvins. From P = nRT/V, changing T from 300 K to 600 K doubles P under those conditions. If the volume expands, the number of moles changes, or pressure itself is constrained, that conclusion no longer follows.
