Unit 12
Chapter Overview
During this unit, students use calorimetry to investigate the amount of heat absorbed or released during a phase change and in chemical reactions using the law of conservation of energy. They perform stoichiometric calculations of enthalpy changes.
Main Ideas
Energy is conserved when heat is transferred.
Energy transformations can be measured in the laboratory.
Water has a unique heating curve.
Chemical reactions are accompanied by energy transformations.
Misconceptions
Students may think heat and temperature are the same.
Students may not understand conservation of energy by means of energy transformations.
Students may not understand the role of friction in energy conservation.
