Conclusions - I

• Related to statements of 2nd law:

• In an ISOLATED system:

  • The system naturally evolves toward more probable configurations
  • The system evolves toward distributing its total energy equally among all its parts (conserving energy of course)
  • Heat flows from hotter to colder bodies
  • The system evolves toward decreasing order
  • The system evolves toward increasing entropy (defined to be a measure of disorder – more later)

• What about:
  • The system’s ability to covert work into heat is always diminishing
