Gas Properties

Gas Properties simulation


  • Ideal Gas Law
  • Kinetic Molecular Theory
  • Diffusion
  • PV Work
  • Maxwell-Boltzmann Distribution

Sample Learning Goals

  • Determine how changing a variable among P, V, N, and T influences other gas properties.
  • Describe the relationship between particle-wall collisions and pressure.
  • Predict how changing temperature will affect the speed of molecules.
  • Predict the speed of molecules in thermal equilibrium based on the relative masses of molecules.
  • Identify when pressure-volume work is done on or by a gas.
  • Explain how two gases mix.
  • Design an experiment to find the factors which affect the rate of diffusion.
