Key Topics to Revise

1

1. Basic Ideas: System, Surroundings, and Types of Systems

  • A system is the specific part of the universe under study with fixed boundaries.
  • The surroundings are the rest of the universe other than the system.
  • Open systems exchange both matter and energy with the surroundings.
2

2. First Law of Thermodynamics and Internal Energy

  • The first law of thermodynamics is the law of conservation of energy.
  • Energy can neither be created nor destroyed, only converted from one form to another.
  • Internal energy U or E is the total energy associated with a fixed amount of a substance under given conditions.
3

3. Pressure-Volume Work and Reversible or Irreversible Expansion

  • Pressure-volume work occurs when the system and surroundings are at different pressures.
  • For expansion of a gas, work done by the system is negative.
  • For contraction of a gas, work done on the system is positive.
4

4. Enthalpy and Heat Changes at Constant Pressure

  • Enthalpy H is the total heat content of a system at constant pressure.
  • H = U + PV.
  • Enthalpy is a state function.
