Internal Energy and Energy Transfers

• What is internal energy stored in?

  Particles (atoms and molecules)
• What is internal energy called?

  Internal energy
• What does internal energy consist of?

  Total kinetic and potential energy of particles
• What changes the energy stored within a system?

  Heating changes the energy
• How does heating affect the energy of particles?

  It increases the energy of the particles
• What happens to the temperature of a system when energy increases?

  The temperature of the system rises
• What does an increase in energy produce in a system?

  A change of state
• What are the components of internal energy in a system?

  • Kinetic energy of particles
  • Potential energy of particles
• What are the effects of heating on a system's energy and temperature?

  • Increases energy of particles
  • Raises the temperature of the system
  • Can produce a change of state
