  1. Ideal Gas Law Janet Penevolpe Karen Glennon

  2. KINETIC THEORY OF GASES • Assumes that the molecules are very small relative to the distance between molecules. • The molecules are in constant, random motion and frequently collide with each other and with the walls of any container.

  3. DEVELOPMENT OF GAS LAWS • Boyle’s Law - relates pressure and volume • Charles’ Law - relates temperature and volume • Avogadro’s Principle - relates to the number of molecules and volume • Ideal Gas Law - relates pressure, temperature, volume, and number of molecules.

  4. IDEAL GAS LAW • An ideal gas can be characterized by three state variables: absolute pressure (P) volume (V) absolute temperature (T). # moles (n) • The relationship between them may be deduced from kinetic theory and is called PV = nRT

  5. GAS PARTICLES Have two elementary actions • They move • They collide with other particles or other objects

  6. We found two models in the NetLogo model library. • Combined and modified these two programs. • Pressure will be a function of the other parameters/variables.

  7. ASSUMPTIONS • All particles average energy. • Minimum number of particles is set at 100 • Minimum temperature is 100

  8. Problems • Volume vs. area calculation • Energy vs. temperature calculation

  9. OUR NetLogo PROGRAM • Ideal Gaw Law Simulation

  10. RESULTS • Learning a new language always creates difficulties. • Harder to copy, read, and modify code than to create it.

  11. MATH RESULTS/VERIFICATION • When volume doubled pressure halved in accordance to Boyle’s Law. • When temperature doubled pressure doubled in accordance with Charles Law. • When number of particles doubled the pressure doubled in accordance with Avogadro’s Principle.

  12. THE MODEL IS VALID because the IDEAL GAS LAW is the COMBINATION OF THESE THREE LAWS!
