A fun way to review Kinetic Molecular Theory is to have students toss a koosh ball at the smartboard to select a question. The answer to each question can be uncovered. There are 25 questions covering areas of the Kinetic Molecular Theory, related atomic concepts and matter. Terms used include phases of matter, particle behavior of solid liquid and gas, ideal gas, pressure, Kelvin, average kinetic energy, temperature, equilibrium, combined gas law, just to name a few. This is perfect for pre-test or review for post-test and NYS regents exams.

Commencement Level Physical Setting, Chemistry
I.3 Subatomic particles contained in the nucleus include protons and neutrons. (3.1c)
I.9 When an electron in an atom gains a specific amount of energy, the electron is at a higher energy state (excited state). (3.1j)
I.10 When an electron returns from a higher energy state to a lower energy state, a specific amount of energy is emitted. This emitted energy can be used to identify an element. (3.1k)
I.12 Atoms of an element that contain the same number of protons but a different number of neutrons are called isotopes of that element. (3.1m)
V.2 The three phases of matter (solids, liquids, and gases) have different properties. (3.1kk)
V.14 The concept of an ideal gas is a model to explain the behavior of gases. A real gas is most like an ideal gas when the real gas is at low pressure and high temperature. (3.4a)
V.15 Kinetic molecular theory (KMT) for an ideal gas states that all gas particles (3.4b):
1. are in random, constant, straight-line motion.
2. are separated by great distances relative to their size; the volume of the gas particles is considered negligible.
3. have no attractive forces between them.
4. have collisions that may result in the transfer of energy between gas particles, but the total energy of the system remains constant.
V.16 Collision theory states that a reaction is most likely to occur if reactant particles collide with the proper energy and orientation. (3.4d)
V.17 Kinetic molecular theory describes the relationships of pressure, volume, temperature, velocity, and frequency and force of collisions among gas molecules. (3.4c)
V.18 Equal volumes of different gases at the same temperature and pressure contain an equal number of particles. (3.4e)
