Ideal gas – pV = nRT in a cylinder

PhysicsThermal Physics & GasesAges 17–18

Gas molecules move randomly inside a cylinder fitted with a piston. Drag the piston to change the volume, slide the temperature bar to heat or cool the gas; the pressure p = nRT/V updates instantly along with a state graph (isothermal p–V, isochoric p–T, or isobaric V–T) showing the theoretical curve and the trace of states visited.
