Science SC2015 (2015) Grade: 9-12 Chemistry | 11 ) Construct an explanation that describes how the release or absorption of
energy from a system depends upon changes in the components of the system.
a. Develop a model to illustrate how the changes in total bond energy
determine whether a chemical reaction is endothermic or exothermic.
b. 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).
