Conservation of Energy

• What can energy be done with in a closed system?

  Transferred, stored, or dissipated
• Why can't energy be created or destroyed?

  It is a fundamental law of thermodynamics
• What does a closed system imply about energy change?

  There can be no overall change in total energy
• What happens to heat in a truly closed system?

  It will always eventually be lost
• In what situation does energy in a closed system fall?

  When heat is lost to surroundings
• What can be assumed about a closed system over short periods?

  It can show complete conservation of energy
• What are the implications of energy conservation in a closed system?

  • Energy can be transferred, stored, or dissipated
  • Cannot be created or destroyed
  • No overall change in total energy
  • Heat will eventually be lost
  • Assumed to show complete conservation over short periods
