  • Kinetic molecular theory

    Theory that helps understand different properties of gases at the molecular level
  • Kinetic molecular theory
    • Gases are composed of molecules
    • Molecules are in constant random motion and frequently collide with one another
    • Collisions are perfectly elastic (no loss of kinetic energy)
    • Attractive and repulsive forces are absent
    • Average kinetic energy of gas molecules is directly related to temperature
  • Avogadro's law
    Gas law that relates the number of moles and volume of a gas, which are directly proportional when pressure and temperature are held constant
  • Solving Avogadro's law problems
    1. Given: v1, n1, v2, n2
    2. Use formula: v1/n1 = v2/n2
    3. Solve for missing variable
  • Ideal gas law
    Combination of Boyle's law, Charles' law, and Avogadro's law, relating pressure, volume, amount of substance, and temperature of an ideal gas
  • Solving ideal gas law problems
    1. Given: p, v, n, T
    2. Use formula: pv = nRT
    3. Solve for missing variable
  • Units for ideal gas law: p in atm, v in L, n in mol, T in K, R = 0.0821 L·atm/mol·K
  • Ideal gas law problems

    • Find moles of gas given p, v, T
    1. Find temperature given p, v, n
