- 7.1: Energy and Chemical Bonds
- Energy is the ability to do work. Heat is the transfer of energy due to temperature differences. Energy and heat are expressed in units of joules.
- 7.2: Heat Changes during Chemical Reactions
- Heat transfer is related to temperature change. Heat is equal to the product of the mass, the change in temperature, and a proportionality constant called the specific heat.
- 7.3: Exothermic and Endothermic Reactions
- Atoms are held together by a certain amount of energy called bond energy. Chemical processes are labeled as exothermic or endothermic based on whether they give off or absorb energy, respectively.
