Physics 212 Lecture: "Thermodynamics I." Jan 19, 1998

• Thermodynamics is the study of heat and work done by systems
• You must keep track of
  • Heat gained (or lost) by a system: Q
  • Work done by (or on) a system: W
  • The change in internal energy of a system: U
• "Thermal equilibrium" means "no heat flows"
• The Zeroth Law of Thermodynamics: If two systems are each in thermal equilibrium with a third, then they are in thermal equilibrium with each other
• The First Law of Thermodynamics: The change in internal energy of a system is the sum of the heat added to the system minus the work done by the system.

This lecture discusses material in Chapter 15 of Cutnell and Johnson.
