Unit Objectives for Chemistry

Unit VI. States of Matter and Gas Laws

PS-6 Kinetic molecular theory, states of matter & Gas Laws- Particles within the specific states of matter differ by internal energies and particle attractions. Understanding how particles interact based on environmental conditions provides the framework for predicting changes in matter.

   TS 6.1 States of matter- The state of a substance is based on the molecular structure, kinetic energy and intermolecular attractions.

6.1.1 Describe particle arrangement & motion in the different states using the kinetic molecular theory of matter

6.1.2 Distinguish exothermic and endothermic processes based on movement of energy

6.1.3 Explain how heat changes (enthalpy) are associated with different states of matter

  TS 6.2 Phase Changes- A change in the state requires a change in the energy of the particles.

6.2.1 Describe the relationship between temperature and states of matter as outlined by warming (cooling) curves

6.2.2 Calculate heat changes (enthalpy) for changes in temperature and states of matter using enthalpy equations

  TS 6.3 Gas Laws- The properties of gases behave in predictable ways which can be described through defined laws

6.3.1 Describe the properties of gases using volume, temperature, pressure & number of particles (moles)

6.3.2 Identify and use the appropriate gas law when quantitatively describing changes in gas properties.

6.3.3 Describe how ideal gases adhere to predicted changes in temperature, volume, pressure and moles.

6.3.6 Calculate partial pressures of gases in a mixture using Dalton’s Law of Partial Pressures
