  • What is thermochemistry the study of?
    Thermochemistry is the study of matter and energy associated with chemical reactions or physical changes.
  • How is energy defined in thermochemistry?
    Energy is defined as the capacity to do work or to produce heat.
  • What are the two main categories of energy discussed in this chapter?
    The two main categories are potential energy and kinetic energy.
  • What does potential energy relate to in atoms?
    Potential energy relates to the position of atoms.
  • What does kinetic energy relate to in atoms?
    Kinetic energy relates to the motion of atoms.
  • What type of energy is associated with chemical bonds?
    Chemical energy is associated with the chemical bonds of atoms and is a form of potential energy.
  • What type of energy is associated with temperature?
    Thermal energy is associated with temperature and is a form of kinetic energy.
  • What is the SI unit for energy?
    The SI unit for energy is the Joule.
  • Who is the Joule named after?
