This document outlines the key concepts and learning objectives for a unit on the matter and thermal properties of materials, including: 1) Describing the thermal expansion of solids, liquids, and gases in terms of the motion and arrangement of molecules. 2) Explaining everyday applications and consequences of thermal expansion. 3) Demonstrating understanding of thermal capacity and how to measure the specific heat capacity of substances. 4) Distinguishing between melting, boiling, evaporation, condensation, and solidification in terms of energy input without temperature change. 5) Defining and providing molecular interpretations of latent heat of vaporization, latent heat of fusion, melting point, and boiling point.
