Matter and Its Interactions
Refine the design of a given chemical system to illustrate how LeChâtelier’s principle affects a dynamic chemical equilibrium when subjected to an outside stress (e.g., heating and cooling a saturated sugar-water solution).
Construct an explanation that describes how the release or absorption of energy from a system depends upon changes in the components of the system.
Develop a model to illustrate how the changes in total bond energy determine whether a chemical reaction is endothermic or exothermic.
Plan and conduct an investigation that demonstrates the transfer of thermal energy in a closed system (e.g., using heat capacities of two components of differing temperatures).
